Software programmable, multi-segment capture bandwidth, delta-sigma modulators for flexible radio communication systems

A receiver module for a transceiver front-end circuit in a vehicle cellular radio, said receiver module comprising:

• a delta-sigma modulator that converts analog receive signals to a representative digital signal, said delta-sigma modulator including;
• a sixth-order LC filter having a plurality of LC resonator circuits, a plurality of transconductance amplifiers and a plurality of integrator circuits, where a combination of one resonator circuit, transconductance amplifier and integrator circuit represents a two-order stage of the LC filter,
• a combiner,
• a low noise amplifier (LNA), and
• a quantizer circuit, said combiner receiving the receive signals and a feedback signal from the quantizer circuit and providing an error signal to the LNA to provide an amplified error signal, said amplifier error signal being provided to the LC filter to provide a filtered error signal, and the filtered error signal being provided to the quantizer circuit.
