Abstract

This research proposed an accurate Duty Cycle Correction (DCC) circuit for high-frequency systems with high measurement accuracy. It is a crucial component of Very Large Scale Integration (VLSI) circuits and is applied as a percentage of the measured average power of a modulated signal to obtain the signal power. This circuit uses two stages of correction, with the first stage performing course correction and the second stage performing fine corrections. This allows the power to be determined during the pulse given the measurement of the average power of a modulated signal with a known duty cycle. DCC have improved stability, correction range, and operating frequency compared with mixed-signal and all-digital DCCs. In this analysis, the duty cycle correction circuits and their significance in Application Specific Integrated Circuit (ASIC) design, along with typical implementation methods, are discussed.
