Abstract
A baseband receiver particularly well-suited for wireless applications utilizes a dual-port DAC in a successive-approximation ADC, where the dual-port DAC replaces the separate pair of single port conventional DACs and is therefore shared by the I and Q down-converted components. The use of a dual-port DAC results in significant size and power savings over conventional arrangements.
