Abstract: PURPOSE:To obtain a circuit using no depletion type FET by defining potential difference generated when a constant current flows to two enhancement FETs, whose threshold voltages are different, as a reference voltage. CONSTITUTION:A mirror circuit 10 is formed by enhancement (EE) FETM4 and M5 and currents I1 and I2, which are determined by the constant ratio of the FETM4 and M5, flow and the current I2 is supplied to a standard EEFETM2, whose threshold voltage is a VTE and gate is connected with a drain.
