Abstract—In this paper, the Linear Superposition technique for Terahertz frequency generation in CMOS circuits has been reviewed. The CMOS circuits are designed in 90nm process and oscillator parameters are designed to have a fundamental oscillation frequency of 91 GHz. Circuit designs for different values of multiplying factor N are demonstrated and their Pspice simulation results are presented and compared. In these simulations, oscillation of up to 910 GHz (for N=10) was observed.
