Problems solved by technology

It should be noted that the gain of the charge-steering differential amplifier 100 is related to the gate-source voltage (V gs ) are closely related, so as long as the differential input signal V i There is a slight perturbation in the common-mode voltage of the output signal V o have a considerable effect, resulting in a decrease in the performance of the charge-guided difference amplifier

Abstract

The invention provides a charging-steering amplifier circuit and a control method thereof. The charging-steering amplifier circuit comprises a charging-steering differential amplifier and a sample hold circuit. The charging-steering amplifier circuit is alternately operated in a reset phase and an amplification phase, thereby amplifying a differential input signal. The method comprises the steps of in the reset phase, obtaining a common mode voltage of the differential input signal according to the differential input signal; in the reset phase, supplying the common mode voltage to one of the charging-steering differential amplifier and the sample hold circuit; in the reset phase, sampling the differential input signal to generate a voltage signal through utilization of the sample hold circuit; and in the amplification phase, inputting the voltage signal into the charging-steering differential amplifier.

Description

technical field [0001] The present disclosure relates to charge-steering amplifiers, and more particularly, to amplifying circuits implemented with charge-steering amplifiers. Background technique [0002] figure 1 is a circuit diagram of an existing charge-guided differential amplifier. The charge-guided differential amplifier 100 is also called a dynamic amplifier, and is mainly composed of transistors 110 and 120 , and further includes switches 130 - 160 and capacitors 170 - 190 . The connection method of each component is shown in the figure. The charge-steering differential amplifier 100 alternately operates in the reset phase (Φ s ) and amplification stage (Φ h ) to amplify the differential input signal V i , and produces an output signal V o . The switches 130 , 140 and 150 are turned off during the reset phase and turned on during the amplification phase, and the switch 160 is turned on during the reset phase and not turned on during the amplification phase. ...
