# Freq Sampling

67 Threads found on edaboard.com: Freq Sampling

im confused with various of definition ? what is conversion rate ? is that conversion rate can be the sampling rate/freq? Or is that sampling rate is clk speed ? how if if a SAR ADC has clk speed of 24Mhz, requires 6 clk cycle to do in that case what will be the conversion rate ? How abt tis Ms/s & Mb/s ? is both same or differ

## AD Converteri/p freq>20kHz and Sampling Rate<0.5usecon

Can someone give me the part number an AD Converter having a sampling Rate of less than 0.5?seconds and input frequency > 20kHz... Please help...

## How to select bandstop & bandpass freq. in iir filter de

The frequencys in discrete time lies in interval from 0 to 1 (or from 0 to 2pi depends on frequency normalisation). Therefore first you have to set sampling frequency Fs in continious time units (Hz). Then any "digital" f character frequency (bandpass or bandstop or any other frequency) of (...)

What 'll happen if the sampling freq is much larger than twice the maximum freq of the signal?

## high accuracy sample and hold

i am using the above sample and hold circuit for a 16-bit ADC> the switch is realised using both nmos(W=500n L=1.6u) and pmos(W=1u L=1.6u). the input voltage range is 0-2v. the sampling freq is sample pulse width is 100usec and hold period is 4.9msec. when in hold mode the voltage at the output first starts increasing and then starts de

## OTA noise simulation in Cadence

Hi all! I've got a folded-cascode OTA with SC CMFB and wanted to look at its output noise. The clock sampling frequency is 64MHz, input signal bandwidth - 2MHz. I used PSS (beat freq 64MHz, 0 output harmonics) and PNOISE (1Hz-32MHz, maxsideband=30, no input noise source) for it. The results that I am getting are quite suprising: http

## What is the relation between Fclk & MSPS in DAC design?

SFDR=Spurious Free Dynamic Range (i.e., the Dynamic Range also accounting for spurious signal) Fout=100MHz I believe indicates that the above figure is measured with a signal sampled at that freq. In eneral SFDR changes for different sampling speed. nathan
