A differential current-mode track-and-hold (T/H) amplifier is used to sample
an analog input signal. A new closed-loop current-mode architecture has been
developed that overcomes the stability problems associated with closed-loop architectures.
The T/H circuit has been fabricated in a 0.35-��m quad-metal, double-poly
CMOS process. The measured total harmonic distortion (THD) is -81dB and -65dB
with an input signal frequency of 100KHz and 10MHz, respectively. This is the best
performance reported to date for a CMOS implementation. / Graduation date: 2003
