Hi Team, I have designed a circuit with a 1.2V dc power supply. Part of the circuit is a clock generator and I output a few clock signals out to test. In order to drive more load, I adopted 4 series-connected inverter buffers before the output pad. Simulation suggested it can deliver 0-1.2V square waves. When I have my IC back, I glued a piece
Hello, as in title "Has anybody tried to run Keras or "Tensor flow" frameworks on FPGAs. I don't ask for runing trained ANN on FPGAs, but I rather asking about running neural networks in training phase. I hadn't eficient Nvidia GPU which is handle CUDA, so I cannot run KERAS on GPU, hence my question about running it on FPGAs. Maybe somebody
Hello, I am working on a project for a course where I am required to design a differential OTA and implement the amplifier's feedback using switched capacitors. I would like to design the switched capacitor feedback network first, while i work out some kinks in my differential OTA, and thus would like to implement the feedback with an "idea
I am developing a test rig for my motor controller. Below is the image which shows a motor is connected back to back to act as a load with load resistor 156455 left side is the controller that will run the motor of 400W. Right side i am connecting another motor with a coupling in between and resistor R1, R2, R3 a
How to extract Voltage of a schematic net? I use ADS. I need to extract voltage of schematic circuit. I can find I_probe and P_probe tools. They work fine. While I can?t extract voltage of a circuit net via V_probe tool. Plz help me. Jade 156454
Hi All, I need to develop an circuit and antenna that will be placed on a person's body, and generate a constant electromagnetic field (for medical purposes). The definitions I received for this project is to generate a field from 10Hz to 700Hz, with field strength of 0.2 mTesla (that is 2 Gauss). I'm not an RF engineer and have (...)

Hi !, my name is Mariah and I am new in this forum. I have come and joined this forum with really high hope that I would get some help from you people. So I have been working for a project that I really want to finish. I want to built a circuit that automatically disconnect after a certain period of time. The time can be manually changed an set by
Hi, i am trying to simulate the mutual inductance of 3D spiral coils for wireless power transfer application. While simulating the coil terminals with lumped port following warning occurs "User Defined Primitive: End edge position: User Defined Primitive: Point0: x = 10.2109956554404, y = 0.00127102124808265, z = 0.5 Adaptive solution setup,
Hi, I use an RFID reader for reading FDX tags. It utilizes ASK modulation so I designed a transformer power supply with LDO linear regulator but somewhere it doesn't work good and read range decreased. I think it's due to poor voltage quality because there are several motors , ... nearby. I utilized an EMI filter in series with P and N. but it s
Hello, Does anyone happen to have video lecture for this stanford course by Prof. Murmann and would like to share it? I have lecture notes for 2004, 2006, 2007, 2009 and 2014 but I wish if I could get the lecture video. Thanks in advance. David
I am designing an energy harvesting system with ring oscillator, non-overlapping clock, and tapered buffer. Shown below is the the clock results and tapered buffer results of the three corners TT, FF, and SS. I was just wondering what causes the poor peak voltages of the tapered buffer results, I expect it to be flat but it is not. Thank you (...)
I am referring to to understand type ii servo loop. Theory provides zero velocity lag for changing velocity inputs. To implement in hardware, I wanted to know if sampling rate is to made higher than the input rate of change? For example, If I desire to imp
Hi, I am looking for thermocouples with readers. I just found one with software support. There is a statement in the user manual / datasheet. I am trying to understand this statement. "RS-232 port to transfer data to PC for analysis" Using RS-232 port to transfer data to PC means that the serial communication protocol is UART ? Is it po
Hi, I am having trouble understanding how a deboo amplifier works. I know how a Howland Negative Impedance works, but I can't understand the effect of the capacitor. Also why is the buffer needed in the input of the circuit? and does a DC offset in the input signal cause the op-amp to saturate? Thanks for the help, I (...)
Hi All, I am new to NXP KW 36. I have done basic programs like led blinking and uart in KW 36. I am going to use this controller for my project for CAN communication. I tried with example also but it is not working. Anyone have idea about this? KW 36A, FlexCAN communication. Thanks in advance.
Hi, What will be the best and low-budget educational materials and platforms? Learning materials and platforms as in books, simulation softwares, development kits (from which manufacturers?), affordable tools. What I already know: 1. C and C++ programming. 2. Python 3. Built a few projects with Arduino 4. (...)
Would analog or digital ICs which aren't attached to a PCB pulled out of their original tape or tube packaging be effected or harmed from few rapid pulses of ~8kG from an air cross over inductor coil? Silicon in chips are semiconductors and back emf can be induced straight onto the junction however most chips can handle 2kv of ESD without issue
Hello everyone, I am currently designing two low noise amplifiers (which will respectively operate at ~20GHz and ~38GHz) with the same foundry process (D007iH from OMMIC). The transistors come as discrete chips (roughly 400x400x100 um) without via holes, the aim is to use inductive degeneration and connect the source pads to ground thanks (...)
