I see the following terms when choosing a hall effect sensor: chopper-stabilization Magnetic type: Bipolar Latch Linear monolithic Omnipolar Transducer Unipolar What do these terms mean?
I am designing an H bridge using the FDMS7556S mosfet. The datasheet states - "This device has the added benefit of an efficient monolithic Shottky body diode." Does this mean that I can omit the flyback diodes?
Actually, it could be as simple as this: 115771 It's a half-bridge design, so you could use any monolithic low-side/high-side MOSFET driver (IR2110) and a cheap MCU/arduino to generate the PWM signal and to manage the output voltage feedback control. The MOSFETs are commonly used N-channel type.

What is difference between Microwave integrated circuits(MIC) and monolithic Microwave integrated circuits(MMIC) I have following doubts (1) Which is chiefer in making and which is costlier in making (2) How to connect ports to the MMIC PCB, because MMIC total size is itself mm or um. (3) How to place components in MMIC technology. (4) How to
I'll give a rough explanation.. imagine monolithic as a big chunk of code running in specific address space...they are not modular because of this very reason, a huge number of lines tightly linked. Furthermore, for the same reason, they are not very tolerant to faults as any error in kernel level, may collapse the entire system (what happen if you
At the time the ua741 was intruduced, the integration of the 30 pF capacitor in a monolithic IC was a technological innovation. The 748 is the same but without internal compensation.
Most silicon transistor datasheets specify a base current of 1/10th the collector current to guarantee a fairly good saturation. You do not assume a base-emitter voltage because it is different for each transistor (unless they are monolithic on an IC) and it depends on the amount of base current. It is from 0.6V to maybe 0.8V for an ordinary little
1. I think, the times when discrete FETs promised an advantage over monolithic OPs for high performance amplifiers are over for 30 years or so. Nevertheless you can get a few suitable devices, for replacement and special designs, e.g. 2. I guess you are asking about monolithic differential pairs? Tw
Timing sign off is not accurate through such lib pins and can be risky. I think you should try to analyze why delays are non-monolithic.
Anyone has RF model +parameters for EC2612 PHEMT from United monolithic semiconductors for ADS simulation?
If you are looking for the drain current in a monolithic MOSFET i.e. an independent NMOSFET/PMOSFET you should look into its data sheet which will give the maximum limits. If you are in the VLSI scale, you should use the Drain current Equation. For an NMOS Id = 0.5 ?n Cox (W/L) (Vgs - Vth)2[/SU
Hi, I need to identify 3 MMIC (monolithic RF amplifiers) markings are E2, E3 and S5, all have the dot which indicates the input below the marking. Plastic package is similar to mar1 Thanks
I just wanted to ask the name of three op amps used in INA114P , i googled the same but was unable to find it. Yes, because INA114 is a monolithic IC, not assembled from individual parts. The question can be answered in two ways: - It 's easy to build a basic three OP instrumentation amplifier circuit, you can do with any gener
Shaiko is right. An IGBT H-bridge would have very poor efficiency. 15 A is apparently unsuitable for monolithic multi-phase ICs. Multi-chip would be feasible, but I'm not aware of low voltage, high current modules. Available "smart power" modules are dedicated for high voltage and moderate currents (a few A maximal).
Have you tried a higher power supply voltage? The TDA2030 is a monolithic integrated circuit in Pentawatt? package, intended for use as a low frequency class AB amplifier. Typically it provides 14W output power (d = 0.5%) at 14V/4Ω; at ? 14V or 28V, the guaranteed output power is 12W on a 4Ω

I've just realised exsistence of monolithic VCOs. Most of them are about <10Ghz. Can it be used as LO in short-range FMCW measuring system? If distance is <5meters, can such VCO be used as stand-alone VCO (without amplification stages on Recieving antenna, etc.). Do I still need some ZCC circuity to control frequency, or such VCOs have well-known
Hi, Does anybody has any architectural schematic diagram or Paper on it. DDC manual doesnt provide much information about design details. Please, post it. If you have it. "A Single-Supply, monolithic, MIL-STD-1553 Transceiver Implemented in BiCMOS Wafer Fabrication Technology " If you have this paper then please pass it. Thank You
In a short, it's effectively impossible in a discrete transistor design without capacitors, because amplifier offsets and offset drifts are too large. An monolithic op would achieve input offset drifts, that allow to substract a fixed DC component. If the DC part is changing however, AC coupling using capacitors would be necessary as well.
Thanks friends for ur suggestions.... But mine is a monolithic DAC and it is a part of an ASIC. It has to bias a sensor inside ASIC. Sensor is biased 0.64v to 1.28v across it where + ve voltage is 3.3v from power supply and -ve voltage is given by DAC and varied insteps of 5mV from 2.02 to 2.66v. And DAC reference voltage are to be gene

You can use a monolithic Amplifier as MAR-8 which can give +12.5 dBm at the output from the available input signal. This circuit is 50 ohms input/output and requires minimum number of external components. Can be DC supplied at 12V using proper bias resistor.

I cannot figure out why in the datasheet of minicircuit amplifier (like ERA3, ERA5, etc) there is a "required" resistor. Suppose I have a power supply of 12 V, and a switching for other function to obtain 5 V. If a monolithic works at 5V, I think the best choice is to apply a voltage coming for example from the switching instead having dissipate

monolithic Microwave Integrated Circuits (MMICs) are used in satellite systems that require smaller, less expensive circuits or when the parasitic reactance inherent in hybrid integrated circuits degrades the circuit performance, typically in the upper microwave and the millimeter-wave spectrum. Examples of systems that use MMICs are receivers

The light-to-frequency converter has a photodiode whose output drives an current controlled oscillator (similar to a VCO). The frequency is therefore proportional to the intensity of the light falling on the photodiode. As the light level increases the frequency increases. The largest provider of such monolithic devices is probably Texas Advan
I don't see a problem to operate a transistor current source in the nA range. You have to check for sufficient low leakage currents of course. But I wonder, if it's an appropriate way to build a current source for a precise measurement. The current transfer ratio even of monolithic current sources is rather variable. I think that high ohmic resisto

The sg3524 has a very good advantage over monolithic cd4047 cus the output can be automatically adjust to normal a.c voltage when there is variation in load. The auto adjust is possible when there is feedback signal to the pin 1 of the ic, the circuit i have worked, but does not have a feedback. thanks.
You must guarantee a common mode input voltage within allowed limits. Usually this doesn't work with a floating source. You need at least high-ohmic bias resistors at the input. Consult a datasheet of a typical monolithic instrumentation amplifier for reference.
I am working on a monolithic CPW 4-way (maybe 8-way in the future) 2watts Wilkinson combiner with center freq 20GHz. BW is 4 GHz. The substrate is GaAs. The size is the major concern in this case.
