Double Balanced Mixer with noise reduction for RF Receiver using Cadence 180nm Technology

RF receiver comprises of local oscillator, mixer and demodulator stages. Mixer circuit has its own roles and responsibility in the receiver circuit. Single stage mixer faces problems like noise, higher order harmonic effects, stability point and higher level of power consumptions. In this paper, we have designed double balancing in mixer with balun circuit, current mirror. These help in reducing the gate to drain capacitance effects and improves the linearity. Simulations are carried out using cadence 180nm technology.
