  • Current mirror utilizing amplifier to match operating voltages of input and output transconductance devices
    Patent number: 6064267
    Abstract: A current mirror utilizes an operational amplifier to provide linear operation over a wide output voltage range. The current mirror includes input transconductance, output transconductance, input cascode and output cascode devices. The operational amplifier has two inputs, one of which is coupled to a node between the output transistors, and the other of which is coupled to a node between the input transistors. The output of the amplifier is used to drive the control terminal of the input cascode device so that the operating voltage of the input transconductance device will be approximately equal to that of the output transconductance device.
