Design and Analysis of Dual Modulus Prescaler Circuit for Frequency Synthesizer

摘要

Our proposed circuits incorporated with dual modulus circuit with additional Logic along with two D latches, which can divide in a ratio of (2/3) by using Current mode Logic (CML) based topology which reduces the delay and consumes very low power consumption of 339.5µW by applying a supply voltage of 1.2V which can drive high frequency up to 20Ghz, with a phase noise and output noise of -128.04dBc/Hz and -137.61dB @ 1 MHz offset respectively.
