Abstract
A receiver is disclosed. The receiver includes an amplifier and a bias circuit configured to provide a bias current to the amplifier. The bias circuit is self biasing. The bias circuit is also configured to adjust the bias current using positive feedback from the amplifier.
Claims20
A receiver, comprising:
- an amplifier;
- and
- a bias circuit configured to provide bias current to the amplifier in response to a bias voltage produced by the amplifier, wherein the bias circuit comprises a first circuit configured to provide self biasing of the receiver by adjusting the bias current using feedback from the amplifier and a second circuit configured to further adjust the bias current using additional feedback from the amplifier.
A method of receiving a signal, comprising:
- providing a bias current to an amplifier from a bias circuit in response to a bias voltage produced by the amplifier, wherein the bias circuit comprises a first circuit configured to provide self biasing of a receiver by adjusting the bias current using a feedback from the amplifier and a second circuit configured to further adjust the bias current using additional feedback from the amplifier.
A receiver comprising:
- amplifying means for amplifying a signal;
- and
- biasing means for providing a bias current to the amplifying means in response to a bias voltage produced by the amplifying means, wherein the biasing means comprises a first circuit means for providing self biasing of the receiver by adjusting the bias current using feedback from the amplifying means and a second circuit means for adjusting the bias current using additional feedback from the amplifying means.
