AbstractThis paper presents a low-voltage, low-power and fault-tolerant implementation of Double Sideband Suppressed Carrier (DSB-SC) amplitude modulator-demodulator circuit for portable communication systems. Through the approximation proposed in this work, a CMOS four quadrant multiplier is used as a (de)modulator circuit to generate DSB-SC (de)modulated signals. Furthermore, the proposed fault-tolerant modem can be used to enhance the reliability of safety-critical communication systems since it is able to provide duplicated output using two path output computations. The proposed circuit occupies a small surface area and is functional at high frequencies even with a low supply voltage. SPICE simulations of the post-layout extracted CMOS multiplier in a full-custom 32 nm CMOS technology, which include all parasitic, are used to demonstrate the electrical behavior of the circuit.
