Claim 15:
16. A method, comprising:
configuring at least two transistors of an amplifier circuit for operation in a saturation region, a first of the at least two transistors being connected to a drive PMOS transistor, a second of the at least two transistors being connected to a drive NMOS transistor;
configuring the drive PMOS transistor and the drive NMOS transistor for operation in a subthreshold region;
powering the amplifier circuit with a supply voltage configured to provide a voltage according to a voltage drop of the drive PMOS transistor and a voltage drop of the drive NMOS transistor; and
output an amplified signal at an output node of the amplifier circuit,
wherein at least one or more resistive elements couple the at least two transistors.
