Abstract:
1. A differential amplifier having high and low states comprising: a first transistor having a first current carrying electrode, a second current carrying electrode, and a control electrode; a second transistor coupled to the first transistor to form a differential pair, the second transistor having a first current carrying electrode, a second current carrying electrode, and a control electrode; a first diode coupled transistor and a first resistor coupled between the first current carrying electrode of the first transistor and a power source; a first output of the differential amplifier coupled between the first diode coupled transistor and the first resistor; a third transistor coupled between the first current carrying electrode of the first transistor and the power source; and a fourth transistor coupled to the control electrode of the third transistor and configured to provide a bias voltage that sets the low state output voltage of the differential amplifier.
