Abstract
An electronic circuit (412) comprises a biasing circuit (414) and an amplifier (416). Biasing circuit (414) biases amplifier (416) with a first current when a supply voltage of electronic circuit (412) is within a predetermined voltage range corresponding to a first supply voltage, and biases amplifier (416) with a second current when the supply voltage is within a predetermined voltage range corresponding to a second supply voltage. The first current and the second current provide separate operating points for amplifier (416), operating points which may, upon design, provide substantially the same operating characteristics. The operating points change with the supply voltage in order to minimize power dissipation. Electronic circuit (412) is suitable for use in an integrated circuit, where it can be used in various electronic systems which provide different supply voltages or have a potential for using lower-voltage technology in the future.
