In addition, the dither signal can be used to dither any remaining non-linearity, and to calibrate offset/gain mismatches in interleaved ADCs. The T/H circuit design also can integrate an amplifier in the T/H circuit, which can be used to improve the signal-to-noise ratio (SNR) of the...

A novel differential output track and hold (TH) circuit with configurable common-mode output voltage is presented. Its structure avoids the coupling circuits required when dealing with different common-mode levels in differential signals. Another novelty of the proposed design is its ability to track...
A high-speed track-and-hold circuit based on picosecond InP optoelectronic switches has been developed with a 260-MHz analog bandwidth, 100-MHz sampling rate, and better than 0.2% accuracy. This circuit, a surface-acoustic-wave convolver, and a charge-coupled-device matrix-matrix-product chip ...
A 8-B 250-MS/S track-and-hold circuit in 0.18-μM CMOS This paper presents a novel design of a high-speed track-and-hold (T/H) circuit, featuring 8-b resolution up to 250 Ms/s and 100MHz bandwidth. It is designed in a 0.18μm CMOS process with a supply voltage of 1.8 Vol...
A track and hold amplifier for use in analog/digital-converters comprises, in succession, an input buffer, a pn-junction switch and hold a capacitor. A feedback is provided between the hold capacitor and the input buffer and a second pn-junction switch is provided to disable the feedback du...
The circuit operates from ±5-V power supplies and is capable of driving a 50-Ω load with ±1-V swings. For a fully differential implementation, the power dissipation is 1.2 W. The amplifier can be integrated either as a stand-alone track-and-hold circuit or as the front end of an ...

Most often the track-and-hold circuit has a gain of 1, but in some applications it can have gains greater or less than 1. When the THA is used with an ADC (either externally or internally), the THA performance is critical to the overall dynamic performance of the combination, and plays...
