Patent ID: 7937064

Claim:
A transceiver amplifier, comprising: a first transistor having a control terminal connected to a first node, a first terminal connected to a second node, and a second terminal connected to a third node; a current source for providing a reference current to the first transistor; a first resistor connected between the second node and the first node for providing a bias voltage to the control terminal; a second resistor connected between the second node and a reference voltage; a first switch connected between the third terminal and ground; and a second switch connected between the third terminal and the reference voltage; wherein the current source is turned on when a control signal has a first value and is turned off when the control signal has a second value, wherein the first switch is closed when the control signal has the first value and is open when the control signal has the second value, and wherein the second switch is open when the control signal has the first value and is closed when the control signal has the second value.
