A 15.5 dB, wide signal swing, dynamic amplifier using a common-mode voltage detection technique

This paper presents a high-speed, low-power and wide signal swing differential dynamic amplifier using a common-mode voltage detection technique. The proposed dynamic amplifier achieves a 15.5 dB gain with less than 1 dB drop over a signal swing of 1.3 V

at an operating frequency of 1.5 GHz with a V
_DD
of 1.2 V in 90 nm CMOS. The power consumption of the proposed circuit can be reduced linearly with operating frequency lowering.
