  • High impedance mirror scheme with enhanced compliance voltage
    Patent number: 6433528
    Abstract: A high-impedance current source 100 having an enhanced compliance voltage. The current source 100 preferably has a means for generating a biasing current 105 and a first current mirror stage having a first transistor M6 coupled to a second transistor M1. A second current mirror stage having a third transistor M2 coupled to a fourth transistor M5 acts as a feedback circuit. A stabilization circuit having a fifth transistor M3 coupled to a sixth transistor M4 are also included. The stabilization circuit is coupled between the first and second current mirror stages and an output circuit having a seventh transistor M7 is connected to the stabilization circuit between the first and second current mirror stages. The current mirror circuit has a low compliance voltage, enhanced operating characteristics and enhanced dynamics which eliminate the need for OTAs.
