Title: Fet amplifier
Inventor: AKEYA MIKIJI
IPC: H03F1/32
Filed: 1993-12-29
Abstract: PURPOSE:To keep optimum the distortion characteristic of the FET due to the environmental change at all times when an analog signal is amplified by using the FET. CONSTITUTION:One of the two FETs constructed on the same element is used for amplifying signals which is made FET 1. The other one is used for control which is made FET 2. The gates of the FETs 1 and 2 are connected. The gate voltage is varied by a variable standard voltage generator to control the drain current. The drain terminal of the FET 1 is connected to the output terminal. The drain terminal of the FET 2 detects the distortion amount by using a band-pass filter 4 passing the frequency where the distortion is generated and a peak detecting device 5 and controls a variable standard voltage generator 7 so that the distortion amount does not exceed a value. Thus, the FET 2 controls the drain current so that the distortion characteristic becomes optimum. As the result, the FET 1 also becomes the optimum drain current.
