A 55-GHz-Bandwidth Track-and-Hold Amplifier in 28-nm Low-Power CMOS.
IEEE Transactions on Circuits and Systems II: Express Briefs(2016)
Abstract
This brief presents a 25-GS/s track-and-hold amplifier (THA) implemented in a 28-nm low-power digital CMOS process. Given the intrinsic low-pass behavior of the THA core, a frequency compensation technique is employed to improve the bandwidth by increasing the input amplitude for higher frequencies. This enhances the small-signal bandwidth by almost 30% to 70 GHz. Large-signal measurements show a ...
