• A structure of a track-and-hold (T/H) circuit based on a pair of complementary floating-gate (FG) MOS transistors is introduced. Its main features include low complexity, low operating supply voltage and gain insensitivity to device mismatches, leading to efficient realization of numerous baseband functions in modern communication systems. The detailed operation and performance analysis of the FG T/H circuit are given. Functional verification of the circuit is provided through a breadboard experiment. The effectiveness of the circuit is verified via simulations where the single T/H cell operating at 10 MHz clock frequency exhibits gain variation less than 0.13% and a dynamic range over 71 dB with the coupling capacitance of 300 fF at 1.5 V supply and 12.75μW power consumption. As a demonstration on its practical viability, the designed FG T/H cell was also utilized to realize a 10 MS/s 7-tap analog correlator for possible use in modern communication applications.
