## Help with output noise and offset?

Dear all, in the cadence environment output noise can be simulated, for bandgap simulations the integrated output noise over 500kHz is about 10uV@dc, input noise 0.5V. The specified source is the supply with 1V ac amplitude. Is there some relation to the offset voltage of the bandgap input stage? Is (...)

## Cadence virtuoso - INPUT question

What is mean by offset voltage and DC voltage in cadence virtuoso? Im asking these parameters regarding SINE input.

## Simulating Offset of Chopper Amplifier

Hi, I'm trying to simulate a Chopper Amplifier input offset voltage in cadence? Does anyone know how to perform this operation? Is there a way to do this using PSS? If so, how? Your responses would be greatly appreciated. Thanks.

## The value of σ in cadence monte carlo simulation

Hi I use two simple voltage sources for input offset in my design. How can I set their σ value in cadence monte carlo simulation? I want to use gaussian function. Rosa

## Corner & Monte-Carlo simulation in Cadence

i also need monte carlo simulation for opamp input offset voltage example. anyone can give a link or send an example

## How to measure the Gm of an OTA in Cadence?

Configure the negative loop back with large R~1GOhm and C~1F (as low pass filter) for offset voltage compensation. Insert ac voltage source Vin with DC bias in series with positive input of OTA. Do AC analysis. Gm=Iout/Vin, where Iout u can measure at the output of OTA. Good luck

## How to simulate offset voltages?

Hello everyone, I use cadence to simulate an amplifiers offset voltage, but it shows the offset is 170mV. I think it's too big. My method is as following: First, I connect the negative input and the output of the amplifier. Then, I add a DC signal at the positive input and sweep DC (...)

## DC-offset cancellation and DC-offset voltage

using negative feedback in baseband amplifiers reduces the DC-offset. does the accuracy of this DC-offset cancellation depend on the magnitude of the input DC-offset voltage? I mean, the higher the input DC-offset voltage is, the better the negative feedback (...)

## Simulating 741 Op Amp

I am trying to simulate the op-amp schematic diagram for a 741 and plot a graph of Power Supply Rejection Ratio v frequency. It is defined as 20 *log( change in dc supply voltage/ change in input offset voltage). Does anyone know how to work this out on the cadence/ PSpice simulator? Do the 2 differential (...)
