Abstract
A digital-analog converter incorporates an array of current source cells connected at the output to a load as a function of an input code subdivided into H and V values, which are most significant bit (MSB) and least significant bit (LSB), respectively. The input code is converted into thermometric codes, respectively HT and VT, whose logic inverses are respectively horizontally and vertically routed to the array. Each position cell (h, v) in the array comprises a first and a second P type metal oxide semiconductor field effect transistor connected in series, and the series is in parallel with at least one third P type metal oxide semiconductor field effect transistor.
