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 method for reducing LO leakage in a radio frequency transmitter begins by producing analog outbound signals from digital outbound signals that represent transmit data. The processing continues by amplifying the analog outbound signals to produce amplified analog outbound signals. The process then continues by mixing the amplified analog outbound signals with a local oscillation to produce mixed signals having an LO leakage component. The processing then continues by attenuating the mixed signals having the LO leakage component to produce mixed signals having reduced LO leakage.

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： An ADSL receiver (200) receives an upstream modified ADSL signal and an ISDN signal from a remote terminal (32) on a twisted-pair copper wire (18). An ADSL transmitter (100) of the remote terminal (32) transmits the ADSL signal in a frequency range above an ISDN frequency range so that the ADSL signal does not overlap the frequency range of the ISDN signal. In one embodiment, the ADSL receiver (200) includes a band pass filter (201), an analog-to-digital converter (203), a decimator (205), a fast Fourier transform (210), and a digital signal processor (212). The decimator (205) converts the ADSL signal back to base band, thus allowing an ADSL signal source to simultaneously utilize the telephone line with an ISDN signal source, without significantly reducing ADSL throughput.

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.
