Abstract: The invention relates to a method of converting a binary word IN(0:P−1) into a thermometric signal T1 . . . TN. In accordance with the invention, this method comprises the following steps: conversion of the binary word IN(0:P−1) into an analog signal Vin, and comparison of this analog signal Vin with a plurality of reference signals Vi (i=1 to N). The invention enables to immunize the thermometric signal from parasitic transitions of the binary word IN(0:P−1). Moreover, this method can be carried out using simple structures consuming little energy, which, in addition, do not lead to substantial decoding delays.

Abstract: A voltage amplifier AD comprising two transistors (Q1, Q2) arranged as a differential pair, having collectors which are connected to a positive power supply terminal (VCC) by means of two branches each comprising a resistive load. One of the branches comprises at least two resistive elements (R21, R22) arranged in series. The amplifier AD is also provided with a third branch comprising a resistive element (R3) arranged in series with a current source (I3). The amplifier AD is also provided with means for comparing the potentials of the different nodes of the circuit, which means allow addition of a first and a second current (IO, IO') to the current supplied in a portion of the resistive load of the second branch. These currents allow rectification of the non-linearity of the evolution of the output voltage (Vout) as a function of the input voltage (Vin).
