Abstract :
A CT quadrature bandpass ADC is designed for a multi-standard television receiver. When clocked at 264MHz, the ADC achieves 90dB of total DR over an 8.5MHz BW centered at 44MHz. The 4th-order 4b ADC uses a modified feedforward topology and includes 12dB of AGC. The 2.5mm2 chip consumes 375mW in a 0.18mum CMOS process
