Patent ID: 8248166

Claim:
An amplifier circuit adapted to amplify an input signal, the amplifier circuit, comprising: a first transistor having a first control configured to receive the input signal, a first non-inverting output, and a first inverting output; a second transistor having a second control, a second non-inverting output, and a second inverting output, wherein the second transistor is configured to be activated by a negative voltage between the second control and the second non-inverting output so that a voltage at the second control is lower than a voltage at the second non-inverting output; a third transistor having a third control, a third non-inverting output, and a third inverting output, wherein: the third control of the third transistor is coupled to the second non-inverting output of the second transistor; and the third inverting output of the third transistor is operably associated with the first inverting output of the first transistor such that the first transistor and the third transistor amplify the input signal to generate an amplified output signal.
