    Abstract: Techniques for providing a jammer-resistant noise-cancelling receiver front end with band-pass impedance matching and good power efficiency. In an aspect, the center frequency of the band-pass impedance matching advantageously tracks the local oscillator frequency. In an aspect, first and second receive signal paths are provided, with an R-C network coupled to the output of the second receive signal path. The resistance of the R-C network may be selected to provide band-pass impedance matching to the RF input signal. The current outputs of the first and second signal paths are combined using a trans-impedance amplifier (TIA). In an aspect, the TIA may be implemented using a dual input transconductor amplifier to further optimize the noise performance and power efficiency features of the disclosure.

    Abstract: A transceiver for reducing transmit signal leakage is described. The transceiver includes a downconverter that downconverts a receive signal to produce a feedback signal. The transceiver also includes a weight learning module that correlates the feedback signal with a transmit signal to obtain a weight. The transceiver further includes a transmit leakage estimator that obtains an estimated transmit leakage signal based on the weight and the transmit signal. The transceiver also includes a transmit leakage reducer that reduces the transmit leakage in the receive signal based on the estimated transmit leakage signal.

    Abstract: Techniques for simultaneously receiving multiple transmitted signals with independent gain control are disclosed. In an exemplary design, an apparatus (e.g., a wireless device, an integrated circuit, etc.) includes a low noise amplifier (LNA) and first and second receive circuits. The LNA amplifies a receiver input signal and provides (i) a first amplified signal for a first set of at least one transmitted signal being received and (ii) a second amplified signal for a second set of at least one transmitted signal being received. The first receive circuit scales the first amplified signal based on a first adjustable gain selected for the first set of transmitted signal(s). The second receive circuit scales the second amplified signal based on a second adjustable gain selected for the second set of transmitted signal(s). The first and second adjustable gains may be independently selected, e.g., based on the received powers of the transmitted signals.
