sfdr of adc
I use binary weighting of digital output data at Cadence calculator like (BIT<7>*2^7+BIT<6>*2^6...) Of course you can use an ideal DAC also. DFT will sample discrete points of this summed data.
ideal sfdr of a dac
You will do a transient simulation, assume sampling with a 500MHz clock, fsampling is 2ns. For 8-bit performance 256 data points is sufficient for FFT. Do a minimum 256*2ns (512ns) transient simulation. Input sinus frequency should be (127/256)*500M. 256 is FFT points 127 is...
analog to digital converter input buffer
I want to drive the Bootstrapped Switch Track and Hold circuit for a 1.5Gs/s, 8 bit CMOS ADC. For 0.18um CMOS process, normal source follower buffer has linearity and gain drawbacks because MOS transistor's output conductance is strongly nonlinear...
