a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
let $g$ be a $p$-group of nilpotency class $k$ with finite exponent $exp(g)$ and let $m=lfloorlog_pk floor$. we show that $exp(m^{(c)}(g))$ divides $exp(g)p^{m(k-1)}$, for all $cgeq1$, where $m^{(c)}(g)$ denotes the c-nilpotent multiplier of $g$. this implies that $exp( m(g))$ divides $exp(g)$, for all finite $p$-groups of class at most $p-1$. moreover, we show that our result is an improvement...
A frequency agile multiplying injection-locked oscillator (MILO) suitable for fast power cycling was designed in 65nm GP CMOS. Edge detectors and multiple injection sites extend the lock range of the x4 multiplier to 36.3% of its free-running frequency. Lock range is further extended to 55.7% (2.3-4 GHz) by using 2 MILOs with adjacent lock ranges. Monitoring circuits identify the correct MILO a...
