A 50% duty‐cycle correction circuit for PLL output

We proposed a circuit for correcting the fluctuations in the duty cycle caused by the increase in the device fluctuations due to the miniaturization of MOS devices and faster operating speeds. This correction circuit uses feedback control consisting of duty‐cycle detection and correction to correct the fluctuations in the duty cycle of a phase‐locked loop (PLL) circuit produced during the

Duty cycle correction using negative feedback loop–An analog solution. In Proceedings of 16th international conference on mixed design of integrated circuits and systems (MIXDES 2009), Lodz, Poland. Google Scholar Mehta, R., Seth, S., Shashidharan, S A

Clock buffer with duty cycle corrector

· If duty cycle distortion occurs, steps are taken to insure that the distortion of the clocking circuit is minimal and the duty cycle is either preserved or corrected. The duty cycle of the clock can be either 50% or non-50% dependent on the applications.

## A fast-locking all-digital deskew buffer with duty …

In this paper, a fast-locking all-digital deskew buffer with duty cycle correction is proposed and implemented. A cyclic time-to-digital converter is introduced to decrease the locking time in conventional register-controlled delay-locked loop to only two input clock

## A Duty-Cycle Correction Circuit for High-Frequency Clocks

We present a circuit to control duty-cycle of high-frequency clocks with very fine resolution. The proposed duty-cycle detection and correction circuits are digital and do not require external references and matching devices. The circuits are designed to compensate for duty-cycle uncertainties in a floating point unit implemented using limited switch dynamic logic (LSDL) (Belloumini, 2005

## Power Factor Correction: What is it? (Formula, Circuit & …

By proper selection of duty cycle, we can get the desired shape of the current to the load. How to Size Power Factor Correction? To size the power factor correction, we need to calculate the requirement of reactive power (KVAR).

## A Duty Cycle Corrector (DCC) using a sigma-delta Analog …

In order to achieve fast duty-correction with a small area, sigma-delta ADC controller used as a duty cycle correction controller. The proposed DCC circuit has been implemented and fabricated in a 0.12-μm CMOS technology. Duty-cycle correctors (DCCs) are

## DLPC34xx Controller Image Calibration

## Electronic Warfare and Radar Systems Engineering …

To express the duty cycle of equation [4] as a percentage, multiply the value obtained by 100 and add the percent symbol. Thus a duty cycle of 0.001 is also 0.1%. The duty cycle can be expressed logarithmically (dB) so it can be added to or subtracted from power measured in dBm/dBW rather than converting to, and using absolute units.

## An all‐digital DLL with duty‐cycle correction using …

Summary This paper presents the design of an all‐digital delay‐locked loop (ADDLL) with duty‐cycle correction using reusable time‐to‐digital converter (TDC). The proposed ADDLL
