Abstract :
An oversampling bandpass cascaded digital-to-analog converter, including digital FIR and analog semi-digital filtering to reduce out of band quantization noise, has been integrated in 0.25-/spl mu/m CMOS technology. The converter has 83 dB of dynamic range for a 6.25-MHz signal band centered at 50-MHz and suppresses out-of-band quantization noise by 40 dB.
