Title: David Castaneda and Precision Sub-RADIX2 DAC Innovation.

Introduction

David Castaneda is an inventor based in Morgan Hill, California. His patent work includes digital-to-analog converter (DAC) designs that use sub-binary radix coding and analog-weight-based calibration. He is associated with Maxim Integrated Products, Inc., and holds 11 patents.

Latest Patents

Castaneda’s latest patent work focuses on precision sub-RADIX2 DAC technology. One described system converts a digital input into an analog output using a sub-radix DAC code. A radix conversion module assigns analog weights to the input’s bit positions and uses those weights to generate the code.

A related design describes an N-bit sub-binary radix DAC that converts an m-bit digital input into an N-bit sub-radix DAC code. Its architecture combines a ladder module with a segment module, whose circuit elements correspond to respective bits of the code. In this design, N is greater than m and equals the sum of the ladder and segment bit counts.
