    摘要： A radio receiver includes a first diversity antenna structure, a second diversity antenna structure, a first RF receiver section, a second RF receiver section, a combining module, and a baseband processing module. The first diversity antenna structure provides the received inbound RF signals from one of the plurality of first antennas based on a first antenna selection signal to produce first received inbound RF signals. The second diversity antenna structure provides the received inbound RF signals from one of the plurality of second antennas based on a second antenna selection signal to produce second received inbound RF signals. The first and second RF receiver sections are operably coupled to convert the first and second received inbound RF signals into first and second inbound baseband signals, respectively. The combining module combines the first and second inbound baseband signals to produce inbound baseband signals.

    摘要： A low power distributed transmitter includes a signal generator, signal partitioning module, signal processing module, a plurality of amplifiers, and a transmitting module. The signal generator is operably coupled to generate a signal to represent base-band data in accordance with a particular transmission protocol. The signal partitioning module is operably coupled to partition the signal into a plurality of signal partitions based on a peak-to-average ratio of the signal. The signal processing module processes the plurality of signal partitions to in accordance with the particular transmission protocol to produce processed signals. Each of the amplifiers amplifies a corresponding one of the processed signal partitions to produce amplified signal partitioned. The transmitting module transmits, via an antenna or a plurality of antennas, the amplified signal partitions as a composite amplified signal.

    摘要： A low power radio transmitter includes an intermediate frequency stage, signal-to-pulse conversion module, and a power amplifier. The intermediate frequency stage up-converts the frequency of a base-band digital signal into an N-bit signal at the intermediate frequency. The signal-to-pulse conversion module converts the N-bit signal at the intermediate frequency into a pulse signal of M-bits at the radio frequency. As such, the signal-to-pulse conversion module is taking an N-bit signal (e.g., an 8-bit digital signal) and converting it into an M-bit pulse signal (e.g., a 1-bit pulse stream). Accordingly, the M-bit signal at the radio frequency is essentially a square-wave, which has a peak to average ratio of zero, is subsequently amplified by the power amplifier.

    摘要： A switched capacitor sample-and-hold circuit which compensates offset voltage error and switch feedthru error while having a one hundred percent duty cycle is provided. Two amplifiers are utilized. A first operational amplifier is disconnected from a second operational amplifier while being autozeroed. An input voltage is sampled onto an input capacitor. The input capacitor is disconnected from the input voltage and then coupled to the second operational amplifier which is in a unity gain configuration. After the sampled input voltage is charged onto an output load, the first operational amplifier is disconnected from the second operational amplifier and the sampling process is repeated. The second operational amplifier is also offset voltage compensated by the first operational amplifier.
