摘要：
A current mirror having improved turn-on and turn-off characteristics capable of operation an expanded voltage range. A cascode circuit comprising a portion of the current mirror is of a high characteristic impedance to increase thereby the voltages over which the current mirror may generate a constant current output. A switching circuit comprised of tandemly-positioned transistors having differing transistor characteristics decreases the transistor turn-on and turn-off times to enhance the characteristics of the current mirror.
