Imaging results based on actual received and simulated waveforms show improvements over the traditional Delay and Sum (DAS) method as well as other MVDR-based methods, in terms of spatial and contrast resolutions. We designed detail circuits that can be configured to implement several of the aforementioned ultrasound beamforming methods effectively. The simulated operating frequency for the circuits implemented in FPGA is up to 62. 5MHz. © 2020 IEEE.adaptive beamforming; coherent plane-wave compounding (CPWC); minimum variance beamforming; Wiener post-filterIntegrated circuit manufacture; Timing circuits; Ultrasonic imaging; VLSI circuits; Beamforming methods; Circuit designs; Coherent plane waves; Contrast resolution; Minimum variance; Minimum variance distortionless response; Operating frequency; Ultrasound imaging; Beamformingconference paper10.1109/VLSI-DAT49148.2020.91964322-s2.0-85093693205
