A cognitive signal converter adapted to produce a digital output signal based on an analog input signal comprises an analog-to-digital converter (ADC) and a cognitive network. The ADC is adapted to produce a digital converted signal based on the analog input signal, a sample clock signal and a process clock signal by sampling the analog input signal in accordance with the sample clock signal and quantizing each analog input signal sample based on the process clock signal. The cognitive network is adapted to receive the digital converted signal of the ADC, control at least one of the sample clock signal and the process clock signal based on the received digital converted signal and one or more characteristics of the analog signal source, and produce the digital output signal based on the received digital converted signal. Corresponding integrated circuit, electronic device and method are also disclosed.

Cognitive signal converter

A time-interleaved analog-to-digital converter for conversion of L analog input signals to L corresponding digital output signals comprises an array of N (N&#x3e;L) constituent analog-to-digital converters each having an analog input and a digital output and each adapted to digitize an analog input sample, and a controller adapted to (for each of the L analog input signals indexed by i=1, 2, . . . , L) select a number N, of constituent analog-to-digital converters from the array of N constituent analog-to-digital converters (wherein N&#x2267;1 and &#x3a3;N&#x2266;N), and cause each sample of the analog input signal to be digitized in a respective one of the selected N, constituent analog-to-digital converters. The analog-to-digital converter also comprises a multiplexer adapted to (for each of the L analog input signals) multiplex the digitized samples of each of the selected Ni constituent analog-to-digital converters to produce the digital output signal.
