Abstract
A circuit for improving amplification and noise characteristics of a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), and a frequency mixer, an amplifier and an oscillator using the circuit are provided. A gate terminal of the MOSFET is connected to a body terminal of the MOSFET through a capacitor and the gate and body terminals of the MOSFET are connected to a current source to simultaneously provide a signal to both the gate terminal and the body terminal, in order to improve amplification and noise characteristics of the MOSFET. As a result, a higher level of amplification and a lower level of noise than the conventional art can be obtained.
