SWITCHED-CAPACITOR CIRCUIT, A RADIO FREQUENCY DEVICE, AND A SWITCHED-CAPACITOR CIRCUIT MANUFACTURING METHOD

摘要

A switched-capacitor circuit, a radio frequency device and a switched-capacitor circuit manufacturing method, relating to discrete capacitance design. The switched-capacitor circuit comprises a first capacitor branch and a second capacitor branch, wherein each of the first capacitor branch and the second capacitor branch has at least one high-resistance resistor; and a transistor connecting the first capacitor branch and the second capacitor branch. This inventive concept effectively reduces the parasitic capacitance when the transistor is in an “OFF” state without affecting the quality factor when the transistor is in an “ON” state.
