The design and implementation of a high speed continuous-time delta-sigma modulator is presented in this report. The modulator is designed for a portable ultrasound digital beamformer to digitize ultrasound signal centered at 3.5MHz with fractional bandwidth of 0.6. A CMOS third-order low-pass modul...
