Abstract: Described are circuits and techniques to increase the efficiency of radio-frequency (rf) amplifiers including rf power amplifiers (PAs) through “supply modulation” (also referred to as “drain modulation” or “collector modulation”), in which supply voltages provided to rf amplifiers is adjusted dynamically (“modulated”) over time depending upon the rf signal being synthesized. For the largest efficiency improvements, a supply voltage can be adjusted among discrete voltage levels or continuously on a short time scale. The supply voltages (or voltage levels) provided to an rf amplifier may also be adapted to accommodate longer-term changes in desired rf envelope such as associated with adapting transmitter output strength to minimize errors in data transfer, for rf “traffic” variations.

Abstract: An encoding technique for reducing the power of PDM microphones is disclosed. Digital MEMS microphones utilize a modulation technique called Pulse Density Modulation (PDM), where a single data line (PDMDAT) is used to convey the digital information from the microphone source to a receiver. A characteristic of PDM is that a low noise signal will produce the most transitions, a zero signal will produce an alternating bitstream of logic-1s and logic-0s, and low noise bitstreams will be rich in singleton and doubleton 1s/0s. Typically, CMOS drivers transmit the PDM bitstream signal. CMOS drivers consume power primarily when they transition, so a bitstream rich in singletons and doubletons will increase power consumption. Differential encoding with an XNOR function is used as a singleton-suppression encoder, and a differential encoding with an XOR function is used as a doubleton-suppression encoder.

Abstract: A clocking technique for reducing the power of PDM microphones in dual microphone systems is disclosed. A clock for a conventional PDM microphone (PDMCLK) is provided by another source. PDM microphones send serial data (PDMDAT) on the rising (“Right”) or falling (“Left”) edge of the PDMCLK clock, depending on how the microphone is configured. In a dual PDM microphone configuration, the microphones alternate sending data on the rising edges (transitions to logic-1) and falling edges (transitions to logic-0) of PDMCLK. Typically, Complementary Metal-Oxide-Semiconductor (CMOS) logic is used to transmit or drive the clock signal to the microphones. CMOS drivers consume power primarily when they transition from a logic-0 to a logic-1 or from a logic-1 to a logic-0. Thus, a free-running clock signal will produce the highest CMOS power consumption.
