“…• The frequency demodulation: as only the sample containing the modulated signal is selected, phase and amplitude information are extracted by removing the carrier. Some modulation can be directly processed such as phase modulation (PSK) by a reading of their phase shifting in their spectrum, amplitude modulation (QAM) or frequency modulation (FSK) [4], [5]. • The concurrent reception: the samples selection is not limited to a lonely RF envelope.…”

This paper presents the principles of a Sampled Analog Signal Processor (SASP) dedicated to Software Radio mobile device. Many technological bottlenecks are to be overcome. The idea is to design a discrete analog signal processor to challenge theses bottlenecks. The main issue associated with the A/D conversion is thus avoided. The SASP aims to select a spectral envelope of a RF signal among all RF signals. To reach that target, the SASP processed analogically the RF input signal spectrum thanks to an analog Discrete Fourier Transform (DFT). Once the spectrum processed, only the voltage samples representing the signal envelope to be treated are converted into digital. The selection of few voltage samples among thousands others replaces the classical mixing and filtering operations. It dramatically reduces the A/D conversion frequency from GHz to MHz frequencies. Design strategy, applications and for the very first time, measurements are presented.

“…However, achieving low power consumption at such high frequencies with an acceptable effective number of bits (ENOB) is not feasible nowadays [8]- [10]. One of the potential methods based on analog pre-signal processing has been proposed to compensate the weakness of the digital methods [11], [12], whose aim is to simplify the analog input signal to the ADC/DSP, thus decrease the bandwidth and power consumption requirement of the ADC/DSP to an acceptable range. Nevertheless, it is inherently difficult for electrical methods to implement a flexible tunable broadband scheme.…”

Digital signal processing has achieved great success in the field of signal processing over the past several decades. However, as the bandwidth requirement increases, the power consumption and effective number of bits (ENOB) of the analogto-digital convertor (ADC) have become bottlenecks. One solution is returning to analog and applying microwave photonic technologies, which shows potential for multiband signal processing. In this paper, a programmable integrated analog photonic signal processor based on cascaded Mach-Zehnder interferometers (MZIs) and a channelized filter has been proposed. Different shapes of the signal processor can be acquired for different applications. The highest processing resolution is 143 MHz, and the processing range of the signal processor can be higher than 112.5 GHz. An application of the signal processor for the signal extraction in a radio frequency (RF) photonic frontend operating from L-band to K-band is presented.
