Hi there,
Ive built a LNA + Mixer + Lo direct down-conversion receiver. flo = frf = 5.2G. However I met lots of trouble when trying to get IP3 and Noise Figure of total circuit.
Cadence cannot perform pss simulation due to non-convergence. At first it's because we have both driving source and autonomous in one circuit. So I add a small source current into LO so that the entire circuit is not autonomous, and add long tstab (30n). But it still doesn't work.:-(
Any comments?
