This brief presents direct measurement of two novel dynamic amplifiers utilizing the "charge-steering" topology. Employing a delayed clocking scheme, a four-stage charge-steering amplifier achieves the highest gain of any reported charge-steering topology. A complementary charge-steering amplifier exploits both charging and discharging cycles to double the throughput while reducing power consumption by 22%. Fabricated in 180-nm technology, this brief presents, for the first time, direct measurement results of charge-steering amplifiers, including gain, noise, linearity, common-mode response, and power supply rejection ratio.
