A wide-range all-digital duty-cycle corrector with output clock phase alignment in 65nm CMOS technology

A wide-range all-digital duty-cycle corrector (ADDCC) with output clock phase alignment is presented in this paper. The proposed ADDCC can correct the duty-cycle error of the input clock to 50% duty-cycle. The acceptable duty-cycle range and frequency range of input clock is from 20% to 80% and from 250MHz to 1GHz, respectively. The proposed ADDCC is implemented on a standard performance 65 nm ...

A Wide Range All Digital Feedback Duty Cycle Corrector

This concise presents a Modified Successive Approximation Register (MSAR)-based duty cycle corrector (DCC), which achieves low jitter, fast lock time with an accurate 50% duty cycle correction. This Modified SAR adopts a binary search method to condense lock time while maintaining tight synchronization between effort and production clocks. The projected DCC consists of a duty-cycle detector, a ...

A counter-based all-digital spread-spectrum clock generator with high EMI reduction in 65nm CMOS

An all-digital spread-spectrum clock generator (ADSSCG) with direct modulation on the digitally controlled oscillator (DCO) is presented. The proposed ADSSCG can generate an accurate triangular modulation on the output frequency, and thus it can achieve high electromagnetic interference (EMI) reduction with a smaller spreading ratio as compared with existing designs. In addition, the proposed f...

A 600kHz to 1.2GHz all-digital delay-locked loop in 65nm CMOS technology

This paper presents an ultra-wide-range all-digital delaylocked loop (DLL). The proposed DLL uses a novel delay circuit which uses the transistor’s leakage current in advanced CMOS process to generate a very large propagation delay. Thus, the proposed DLL can operate at very low frequency with small chip area and low power consumption. The proposed DLL can operate from 600 kHz to 1.2GHz in the ...

Duty-Cycled PLL for Wireless Sensor Nodes in 65nm CMOS

The design of a Duty-Cycled PLL (DCPLL) capable of burst mode operation is presented. The proposed DCPLL is a moderately-accurate low-power high-frequency synthesizer suitable for use in nodes for Wireless Sensor Networks (WSN) applications. Thanks to a dual loop configuration the PLL’s total frequency error, once in lock, is less than 0.25% from 300 MHz to 1.2 GHz. It employs a fast start-up D...
