Abstract
A device for continuous time quantization of an input signal, in order to supply a continuous time output signal that is quantized as two bits, the device including: an electronic circuit, designed to supply a first bit of the output signal called the sign bit which at any time takes a first value when the input signal is positive and a second value when the input signal is negative, and an envelope analysis circuit designed to supply a second bit of the output signal called the envelope variation bit which at any time takes a first value, called high value, when an envelope signal of the input signal is increasing, and a second value, called low value, when the envelope signal is decreasing.
