Abstract
Digital information can be represented by Quadrature Phase Shift Keying (QPSK) modulation scheme. In order to represent digital data, a finite variety of different signals is used in modulation schemes. For the representation of digital signals, QPSK uses four unique phases. Due to the key features and performance efficiency in bit error rate and optimal bandwidth, QPSK is commonly used in several modern digital communication based applications. Satellite, wireless and mobile communication uses this technology. QPSK modulators made with mux, counters and balanced modulators are already available in the market. Due to the use of transformers for making these devices, they turn out to be bulky. This paper propose a general purpose IC based novel QPSK modulator. This efficiently reduces the size and thereby the complexity of the circuit.
