for reducing flick noise of folded cascode amplifier, choppered with frequency 1Meg, with spectre rf simulation pss + pnoise, the output noise is as fig. a1 below shows , why not like a2 shows, is my simulation setup wrong?
I want to know whether NQS model is included in TSMC.18 model when NF is simulated in Cadence SpectreRF.
NF I postlayout- simulated is about 1.3 dB in consideration of
LNA's matching network and pad parasitics , package and corner fluctuation at room temperature. but, after testing, i found...
I have designed lograthmic amplifiers for RSSI of tranceivers, but found that the log amp's output changed greatly with process and temperature. The bias i used is the current generated from bandgap. How to fix this problem, make the logamp's output stable with temperature and process. 3X
I have designed a LNA for wide-band application. After finishing layout and postsimulation, i found mismatching of input and output make the noise figure deterioation. But ,presimulation shows matching is good. Is the result believable?
How to improve it?
i have designed a l transimpedance amplifier for optical preamplifier,
i needed designing an AGC for controlling the overload of optical power, but i don't know the theory of CMOS peak detector, can you recommend some paper about CMOS AGC and peak detector？

asitic cygwin
after i installed cygwin, i run asitic_cygwin -t sample1.tek
but failed reading .asitic init fail fatal error:could not open display...
what's the problem of
hspice sparameters s12
i wrote a program for LNA, but failed getting accurate s-parameter , only acquiring
accurate S22 parameter, why? following is the control program

X2 2 3 4 LNA_CORE
X3 2 3 BIAS
X4 4 5 OMN
