Title:
CIRCUIT AND METHOD FOR COMPENSATING OUTPUT OF VOLTAGE SOURCE, AND VOLTAGE SOURCE
Document Type and Number:
WIPO Patent Application WO/2021/232426
Kind Code:
A1
Abstract:
The present disclosure relates to a circuit and a method for compensating output of voltage source, and the voltage source. The circuit (20) for compensating an output (Vo) of a voltage source, comprises: a sensing unit (202), a first adjustment unit (102), an amplifier unit (205), and a second adjustment unit (101). The first adjustment unit (102) is coupled in parallel with the sensing unit (202), and configured to generate at least one pole point and/or at least one zero point in a transfer function of the circuit (20); the second adjustment unit (101) is configured to generate at least one zero point in the transfer function of the circuit (20). Therefore, the first adjustment unit, and the second adjustment unit are arranged for generating adjustable zero points and pole points in the transfer function of the voltage source, so as to obtain a higher loop bandwidth.
