Patent ID: 7486936

Claim:
An integrated circuit radio transceiver, comprising: a baseband processor operable to process ingoing digital communication signals and to produce outgoing digital communication signals; a transmitter front end operable to process and transmit outgoing RF signals based upon the outgoing digital communication signals; a receiver front end operable to receive ingoing RF signals and to process the ingoing RF signals to produce the ingoing digital communication signals to the baseband processor; a linear regulator with over-current protection operably disposed to regulate a power supply for providing power to at least a portion of one of the transmitter and receiver front ends, the linear regulator further including: an output transistor operably disposed to produce a limited output signal to a regulator; an amplification block for producing a bias signal for the output transistor; and a current steering amplification block for providing a limiting bias signal to adjust and limit the bias signal to the output transistor whenever an output current magnitude of an output current exceeds a threshold.
