Abstract
A track-and-hold is a critical sub-circuit of a wideband pipelined ADC. A 1-GS/s fully differential dual track-and-hold circuit fabricated in an 80-GHz f/sub T//fax, GaAs HBT production process exhibits an input bandwidth of 8.4 GHz (0.5 V/sub pp/) and 9.3 GHz (small signal). Total harmonic distortion is -59 dB for 1-Vpp 1-GHz input, and -42 dB for 0.5-V/sub pp/ 5-GHz input. The chip occupies 0.9 mm/spl times/1.8 mm active area and consumes 2.2 W from /spl plusmn/5 V.
