Abstract:
1. A receiver in a packet based communication system, the receiver comprising: a programmable block; a detection block that detects at least one of an operating condition of the receiver and a protocol condition of the communication system; a control circuit coupled to the programmable block that controls the programmable block to transition to a set of radio modes according to at least one of the operating condition and the protocol condition, wherein the set of radio modes comprises a semi sleep mode, wherein the semi sleep mode corresponds to a silent state where the receiver is configured to be idle and ready for a rapid transition to any of the set of radio modes, wherein a performance of the programmable block is selectively degraded according to the operating condition to optimize power consumption; a bias circuit that is in active state to reduce the transition time.
