A Radio-Frequency Real-Time Spectrum Sensor based on an Analog Signal Processing Magnitude Calculator
Résumé
This paper presents a wideband CMOS FDSOI fully-balanced analog multiplier which is part of a magnitude calculator for real-time spectrum sensing. Simulations based on a 28nm CMOS FDSOI technology show that the proposed multiplier offers 13.8GHz bandwidth when loaded by a high capacitance with a power consumption of 343uW under a 1V supply. Multiplication between high frequency voltage samples satisfy properties of common multiplication in arithmetic and can be useful in analog signal processing such as real-time spectrum sensing.
