| dc.description.abstract | A sample clock generator circuit for an analog beamformer is implemented by using a NOR-type MASK ROM look-up table and digital blocks. To reduce the size of the look-up table, the sampling time interval is kept constant until the error reaches ±4Ts (Ts : period of 160MHz clock) and it is either increased or decreased by only one Ts per step. The look-up table stores the focal point number and the UP/DN code. The size of the look-up table is 1.97Mbit for a 64-channel transducer with the maximum delay of 7.9usec. | en_US |
