Behavioral model of a noisy VCO for efficient time‐domain simulation

Abstract

superior isolation performance of the mixers is attributed to the precise control of the length for each stub in the circuit, as well as the APDP's antisymmetric characteristic of mixing a more stable quarter frequency of the fundamental signal. CONCLUSIONA high-performance V-band quadruple subharmonic MIMIC mixer circuit has been proposed and demonstrated in this work for millimeter-wave down-converter applications. The proposed subharmonic mixers show good conversion-gain and isolation characteristics. The fabricated circuits operate in an RF frequency range of 58. 4 -62.4 GHz at an IF frequency of 2.4 GHz, and in an LO frequency range of 14 -15 GHz. An excellent conversion gain of 0.8 dB is obtained at an LO frequency of 14.5 GHz and an LO power of 12 dBm. Regarding the operation frequency range of the mixers, both LO-to-RF and LO-to-IF isolations are higher than 50 dB. BEHAVIORAL MODEL OF A NOISY VCO FOR EFFICIENT TIME-DOMAIN SIMULATION
