I am not checking your code! I want to give the input in code itself.I don't want to use testbench to give different serial inputs. A test-bench is highly recommended. Your design/logic needs to interact with the outside world. The top-level ports are the path-ways for your design/logic to receive and output data. How do you feed-i
No. Don't do it. First perform a level-shift and then divide the input voltage. This can be done by applying superposition techniques.
Hi folks, I have four nMOS switches connected in Series with flying cap to boost input voltage to higher level ( circuit schematic attached). I am driving them using Arduino which has capability of 20mA/pin, my switches need only 5mA/switch, So I think I don't need a gate drive. The problem I am facing now how to shift the signals for upper swit
Hello, I am facing problem that my cmos layout internal connection (drain, source, gate) are not showing. It only shows black boxes or top-level. I tried AV, stop level to 32 , shift+f. but it's not working. I see assura_techfile is there but I don't know why its not working. I have attached snap. can anyone please help in this regard. I (...)
The same diodes + voltage divider level shift circuit can be found in many controller ICs with internal error amplifier. May be they just copied a design template. I don't see the purpose of asking "what's the purpose of". Just take it as is. The specified characteristic is achieved with this circuit in place.
Why don't you understand that a gain (an increase) of -1.5 is not attenuation, it is a gain (an increase) of 1.5 times but the output is inverted (180 degrees phase shift from the input phase)? A gain of -10 is a gain (an increase) of 10 times and again the output is inverted. A gain of +0.1 is attenuation where the output level is 1/10th the input
128912 1)first stage of 2 series diff amp. It says its level shifting. What level does shift from and to? 2)at the output stage, two inverter with their output tied together. What's purpose of that?
The circuit does in fact a negative instead of the intended positive level shifting. Quite obviously, a single supply non-inverting amplifier can't process the negative input voltages corresponding to negative currents. A simple way to achieve a positive level shift is to use two resistors and a reference voltage. No OP needed.
Hello The input of my circuit is between -1 to +1. I need to shift the voltage level to 0-2 to measure the signal with an ADC. My whole circuit is single supply and works with +5. My signal is DC-coupled. Anybody can help me design a voltage shifter for this board?
Hi, guys, I have a question about the interface between sensor and ADC. I have a power detector that produces voltage levels ranging from 0.26V to 1.1V. My selected ADC input voltage range is 0-3.3V. My question is that is that really necessary to build a interface using op-amp to map 0.26V to 0V and 1.1V to 3.3V accordingly? Since the range
Would you mind to draw a transistor level circuit and explain where you see two signal inversions respectively 360 phase shift? Obviously there's only one signal inversion, switching the loop phase by 180 degree. The oscillation condition could be fullfilled if the loop gain has three poles providing additional 180 degree phase shift. (...)
What are disadvantages of inverter as level shifter? Why we can't use it?
I have a 3.3V AC voltage source. I want to level shift it by 3.3V (D.C. level shift). The circuit should work like a clamper circuit. How can i possibly design a circuit for the same? Is there any IC which does the same?
There are shift operators in VHDL but they should not be used. See rule C_31 in this collection of mostly good coding rules: I wouldn't classify 'Rule C_31' in the category of 'good' rules. What is the reason for banning integer and std_ulogic for synthesizeable code? I think integer with a range can sometim
Hello, Here are simulations ( in the free LTspice) of a Full Bridge SMPS, and a Phase shift Full Bridge SMPS. Why is it that the phase shift full bridge smps has a dc bias level in its magnetising current? (you can see the magnetising current by pasting the supplied expression in the simulation schematic into the waveform window, using (...)
I would have a level shifter then a non inverting gain of about 3.3
If you are looking only to shift the frequency, any RF mixer would follow at its IF output the RF input level, if the mixer is not in compression (RF input level is below P1dB of the mixer). So, you can use any standard DBM (double-balanced mixer) which will preserve your modulation and levels.
Below is difference between all 3 constraitns : ATPG constraints : applied for shift and capture both Cell constraints : applied to scan cell only. PI constraints : apply to Top level Input only and effect during capture only. Hope you understand. Regards, Maulin Sheth
I have a RF Frontend that has an 4 IF signal output (2 I channel and 2 Q channel from 2 receiving anettans). Each channel of the IF has a signal rangining from 1.5V to 3.5V with a DC offset of 2.5V. IF output signal: 111250 I want to sample the signal with an ADC that has a reference voltage from 0 to 5V and use th
Are you considering the fact that resistor terminal voltage must be inside the Vss to Vdd range? Means a 0..-5 negative regulator needs Vss =-5, Vdd = 0V and level shift for the control inputs.
