Abstract
An array of ultrasonic transducers can be controlled to produce a steerable beam. Beam steering can be skewed by buffer delays in the distribution of a clock signal. The skew can be at least approximately linearized by distributing the clock signal in a diagonal fashion across an array of buffers corresponding to ultrasonic transducer controllers. Potential error in beam steering that can arise from clock skew can be corrected based on the linear tilt.
