Abstract: A cellular radio architecture that includes a receiver module having a delta-sigma modulator that includes a plurality of gm cells configured in stages, where each stage includes at least two gm cells and an LC filter circuit. The gm cells in each stage can be controlled to be active or inactive to convert, for example, the modulator from a fourth order modulator to a second order modulator to reduce power dissipation. Further, the gm cells can be controlled to optimize a dynamic range of the modulator and to redirect current from inactive cells to active cells in order to optimize power consumption.

Abstract: A transceiver front-end circuit for a cellular radio architecture for a vehicle, where the transceiver circuit employs components for reducing power consumption. The transceiver circuit includes a receiver module having a delta-sigma modulator that converts analog receive signals to a representative digital signal in an interleaving process, where the delta-sigma modulator includes a combiner, a low noise amplifier (LNA), an LC filter and a quantizer circuit. The LC filter is a multi-order filter and the quantizer circuit is an interleaving quantizer circuit that interleaves multiple groups of bits from the filter. The order of the LC filter is selectively reduced in situations where a full dynamic range of the cellular radio is not required and a bit resolution of the quantizer circuit is reduced so as to reduce the power requirements of the cellular radio.

Abstract: A system and method for employing BLE nodes in a PEPS system to determine whether a FOB is within or outside of a vehicle. The method includes interrogating the FOB using a signal transmitted by a BLE device on the vehicle to determine whether the FOB is in a predetermined vicinity of the vehicle and receiving a Bluetooth signal at the BLE device that is transmitted by the FOB if the FOB is in the vicinity of the vehicle. The method also included determining a transmit power of the Bluetooth signal transmitted by the FOB and determining a receive power of the Bluetooth signal transmitted by the FOB and received by the BLE device. The method uses the transmit power and the receive power in a comparison process to determine whether the FOB is inside or outside of the vehicle.
