Title: Resistive element by mos fet
Inventor: MIYAZAKI TOMOHIRO
IPC: H01L27/06
Filed: 1987-02-17
Abstract: PURPOSE:To prevent the non linearity of an ON-resistance with respect to the change in an output voltage VOUT by providing a MOS FET, a buffer amplifier buffering a voltage of a source terminal and a level shift circuit shifting its output voltage to drive a gate of the MOS FET so as to constitute the resistive element. CONSTITUTION:The voltage VOUT at an output terminal 2 is inputted to a level shift circuit 5 via a buffer amplifier 4. The level shift circuit 5 generates an output voltage VDDO when the voltage VOUT at the output terminal 2 is a value VOUT0 being a reference and generates an output voltage VDDO+ or - V when the input voltage is VOUT0+ or - V. In this case, in taking notice of a gate-source voltage VGS of the N-channel MOS FET 3, the voltage VGS=VDDO-VOUT0 with VOUT=VOUT0 and the gate-source voltage VGSX is expressed as VGSX= VDDO-VOUT0=VGS with VOUT=VOUT0+ V. Thus, the voltage VGS is kept constant with respect to the change in the output voltage VOUT.
