Patent ID: 8525717

Claim:
Circuitry comprising: in-phase circuitry comprising an in-phase pair of analog-to-digital converters (ADCs) adapted to provide an in-phase pair of sub-quadrature output signals based on an analog in-phase input signal, wherein each of the in-phase pair of ADCs has about an analog-to-digital converter (ADC) bandwidth and the in-phase circuitry has an input bandwidth, which is about equal to two times the ADC bandwidth; quadrature-phase circuitry comprising a quadrature-phase pair of ADCs adapted to provide a quadrature-phase pair of sub-quadrature output signals based on an analog quadrature-phase input signal; and digital complex processing circuitry adapted to process the in-phase pair of sub-quadrature output signals and the quadrature-phase pair of sub-quadrature output signals to provide a digital in-phase output signal and a digital quadrature-phase output signal, wherein the in-phase circuitry, the quadrature-phase circuitry, and the digital complex processing circuitry provide a half-bandwidth based quadrature ADC.
