摘要
Abstract
A fully-differential master-slave track-and-hold amplifier (MS-THA), with 20 GHz bandwidth isdesigned and fabricated using 0.13 μm SiGe BiCMOS technology. The MS-THA employs conventional switched-emitter-follower (SEF) as track-and-hold core circuit, Cherryhooper circuits as band-boosting of input buffer and output buffer. To verify the validity of the above circuits, a single-stage THA is designed together with the MS-THA. Operating with a single +3.3 V supply, 0 V input direct-voltage, 2 G/s sampling and ?3 dBm input power, the MS-THA achieves a single-ended spurious free dynamic range (SFDR) of less than ?23.5 dB at frequency of up to 20 GHz, and total power consumption of about 300 mW.关键词
