Abstract
The present disclosure discloses a dynamic amplification circuit, including: a first drive circuit, receives a first control signal to generate a first and a second voltage signal; a second drive circuit, receives the first and the second voltage signal to generate a first drive signal; a third drive circuit, receives the first control signal and the first drive signal to generate a second control signal; and a dynamic amplifier DA, controls a first and a second control switch according to the control signals; in a first time period, the first control signal is high level, the second control signal is low level; in a second time period, the opposite is the case; in a third time period, the first and the second control signal are both at low level, a duration of the second time period is inversely proportional to a transconductance of a transistor in a saturation region.
