In this paper, a new compact, low power and low voltage structure for CMOS analog multiplier is proposed. All of them are implemented using a compact circuit. The circuit is designed and analyzed in 0.18µm CMOS process model. Simulation results for the circuit with a 1.2V single supply show that it consumes only 25µw quiescent power with 2GHz(More)
New analytical equations are proposed for oscillation amplitude of the MOS Colpitts oscillator. These equations are obtained from a large signal analysis. The analysis is based on a reasonable estimation for the output waveform. The estimated waveform should satisfy the nonlinear differential equations governing the circuit. The validity of the resulted(More)
In this paper a new highly linear CMOS mixer is proposed that utilizes simultaneously second and third-order distortion cancellation using second harmonic injection, and an in-depth analysis of the mixer is presented. Simulations in a 0.18 μm CMOS technology demonstrate that IIP3 and IIP2 of the proposed mixer have 10dB and 26dB improvements,(More)
SUMMARY In this paper, closed-form analytical equations for the time-domain amplitude of the MOS cross-coupled oscillators are derived. The procedure of the paper is based on estimating an accurate equation for describing the behavior of the cross-coupled MOS configurations and finding a reasonable solution for the nonlinear differential equation governing(More)
