Abstract

An object is to obtain an amplification circuit which provides a high gain even with a low-voltage power supply. The amplification circuit comprises an MOS transistor (M1) having a gate receiving an amplified signal (RFin), a source electrically connected to ground, and a drain electrically connected to a supply voltage (VDD), wherein the back gate-source voltage (Vbs) of the MOS transistor (M1) is made larger as the gate-source voltage (Vgs) of the MOS transistor (M1) becomes larger, thereby making the threshold voltage (VT) of the MOS transistor (M1) smaller.
