Design of an All‐Digital Synchronized Frequency Multiplier Based on a Dual‐Loop (D/FLL) Architecture
VLSI Design, Volume 2012, Issue 1, 2012., 2012 This paper presents a new architecture for a synchronized frequency multiplier circuit. The proposed architecture is an all‐digital dual‐loop delay‐ and frequency‐locked loops circuit, which has several advantages, namely, it does not have the jitter accumulation issue that is normally encountered in PLL and can be adapted easily for different FPGA ...
