Circuit Implementations and Comparison between Different Multiplication Factors in Terahertz Frequency Generation in 90nm Process Using Linear Superposition
Keywords:
Terahertz frequency generation, linear superposition, terahertz CMOS circuitsAbstract
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.
