| 主权项 | 1. A reference voltage generator, comprising: an electrostatic discharge (ESD) resistor; a first branch coupled to the ESD resistor and including a first capacitor; a second branch coupled to the ESD resistor and including a second capacitor, wherein the first and second capacitors are coupled in parallel; a first switch configured to control a first charge transfer path leading to the first branch; and a second switch configured to control a second charge transfer path leading to the second branch, wherein the first switch is controlled by a first clock signal and the second switch is controlled by a second clock signal, wherein at least one of frequency and duty ratio of the first clock signal is changed for tuning a resistance value of the ESD resistor. | ||
