A 375-mW Quadrature Bandpass \Delta\Sigma ADC With 8.5-MHz BW and 90-dB DR at 44 MHz

A 375-mW Quadrature Bandpass \Delta\Sigma ADC With 8.5-MHz BW and 90-dB DR at 44 MHz

A quadrature bandpass DeltaSigma ADC for a multistandard TV tuner achieves a total dynamic range of 90 dB over an 8.5-MHz passband centered on 44 MHz while consuming 375 mW. The fourth-order continuous-time ADC uses active-RC resonators configured in a modified feedforward architecture
