Abstract
An apparatus having an electronic amplifier with signal gain dependent bias. The electronic apparatus includes the amplifier and a bias state control circuit. The electronic amplifier has a signal gain and a bias state. The signal gain is adjustable to either of at least two different signal gain settings, and the bias state is adjustable to either of at least two different bias state settings. The bias state control circuit has capability of adjusting the bias state setting of the amplifier based upon the signal gain setting to which the amplifier is adjusted.
Claims20
An electronic apparatus, comprising:
- an electronic amplifier having a signal gain and a bias state, wherein the signal gain is adjustable to either of at least two different signal gain settings and wherein the bias state is adjustable to either of at least two different bias state settings;
- and
- a bias state control circuit, wherein the bias state control circuit has capability of adjusting the bias state setting of the amplifier based upon the signal gain setting to which the amplifier is adjusted.
The electronic apparatus as recited in claim 12, wherein the bandwidth to which the amplifier is adjusted is set automatically as the bias state setting is set.
An electronic apparatus, comprising:
- an electronic amplifier having a signal gain and a bias state, wherein the signal gain is adjustable to either of at least two different signal gain settings, wherein the bias state is adjustable to either of at least two different bias state settings, and wherein the bias state setting to which the amplifier is adjusted is dependent upon the signal gain setting to which the amplifier is adjusted.
A method for adjusting a bias state of an electronic amplifier, comprising:
- receiving a required gain control signal for the electronic amplifier;
- adjusting signal gain of the electronic amplifier in compliance with the required gain control signal, wherein signal gain is adjustable to either of at least two different signal gain settings;
- determining appropriate bias state setting;
- adjusting bias state of the electronic amplifier to the appropriate bias state setting, wherein the bias state is adjustable to either of at least two different bias state settings and wherein the appropriate bias state setting to which the amplifier is adjusted is dependent upon the signal gain setting to which the amplifier is adjusted.
