摘要:
In a reference voltage generating circuit, in a first period, only a first switch is OFF and a maximum peak value Vmax of an input signal In is held at a node A of a first capacitor 1. Next, in a second period, a second and a third switches are opened, and a voltage difference between the maximum peak value Vmax and a minimum peak value Vmin is held at a node C of a capacitor string. At this time, the voltage held in a second capacitor of the capacitor string is added to the voltage held in the first capacitor, and the voltage at a node B is output as a reference voltage Vref. The input signal In is applied to one input terminal of a differential amplifying circuit, and the reference voltage Vref is applied to the other input terminal. When the voltages held at the nodes A and C have stabilized, the reference voltage Vref is generated. Accordingly, there is provided a voltage amplifier that can amplify input signals having a variety of signal amplitudes to a constant amplitude by using the reference voltage generating circuit with excellent high-speed response.
