Abstract
A closed-loop current-mode track-and-hold (T/H) has been designed and fabricated in a 0.35μm 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. The T/H features a highly linear transconductor and stability enhancement through feedback compensation.
