Design of QAM in 45nm Using Cadence Tool

For wireless communication, low-power modulators are Widely used because of their efficiency. Quadrature Amplitude Modulation (QAM) is one of the popularly employed modulation Techniques for high data rate transmission. This paper describes the analysis of the parameters like power and area of 32bit and 64bit QAM modulators. In this proposed approach, a Lookup table is used to store cosine and sine wave data generated using traditional methods. To generate the output signal, the stored data is chosen on the input data stream. The modulator is simulated and synthesized, and results are compared in 180nm, 90nm, and 45nm in Cadence’s genus tool. The proposed model is designed and developed in Verilog code using cadence. The layout of the 64qam modulator is carried out in the cadence’s innovus tools with 45nm technology.
