Abstract: An automatic gain control (AGC) method and system for a radio receiver are proposed in which the ACG comprises two AGC loops; a first loop controlling signal gain in the analogue portion of the radio receiver, a second loop controlling gain in the digital domain after digitization of the received signal. The analogue AGC loop has a slower response time than the digital AGC loop. When applied to a multi-branch diversity receiver, each branch has its own digital AGC loop, but the analogue gain can be common to all branches, based on measurement of the analogue signal in each branch.

Abstract: A power management integrated circuit comprises a plurality of power source circuits power received at a power supply input terminal to supply power to a plurality of power supply output terminals. A plurality of power source circuits is coupled between the power supply input terminal and the respective power supply output terminals. The power management integrated circuit comprises an active configuration memory and a communication interface with at least one terminal for uploading configuration data from outside the power management integrated circuit into the configuration memory. A control circuit controls operating parameters of respective ones of the power source circuits dependent on the configuration data from the active configuration memory. Thus, the power management integrated circuit is able to switch between different power supply states in a dynamically configurable way, without requiring external control over the configuration during switching.

Abstract: A modulator comprises a polar generation stage that generates an amplitude and phase component of a modulation signal, a differentiator stage that generates a differentiated phase component by differentiating the phase component; and an event detection stage that detects a high bandwidth event by detecting the amplitude component and/or the differentiated phase component meeting an event criterion. An inversion stage generates a modified amplitude component by inverting the amplitude component in response to detecting the high bandwidth event. A phase offset stage generates a modified differentiated phase component by, in response to detecting the high bandwidth event, adding to the differentiated phase component a phase offset having a magnitude of 180° and a sign opposite to a sign of the differentiated phase component. Amplitude and phase modulation stages employ the modified amplitude component and the modified differentiated phase component to respectively modulate the amplitude and frequency of a carrier signal.
