The present paper introduces a resonant clock generation and distribution scheme that uses uniform amplitude and uniform phase standing wave oscillators in order to distribute a high-frequency clock signal with low skew, low jitter, and low power. A suitable distributed resonator for a global clock distribution that is inductively loaded transmission line generating a uniform amplitude and uniform...
A 3.57-Gb/s, low-power, 2 31-1 output length, extended frequency range Pseudo Random Binary Sequence (PRBS) generator with an improved wave-pipeline technique is presented. The previous wave-pipeline technique bypasses the portion of feedback loop, and thereby relaxes the timing restriction of the critical path up to two shifting clock periods. While the generator operates at the 48% higher frequency...
A clock distribution network using inductively-loaded standing-wave oscillators is designed. Synchronization among oscillators is achieved through magnetic coupling. The 12GHz clock distribution network is prototyped in a 6M 0.18mum CMOS technology. A peak-to-peak jitter of 4.7ps is achieved on a 5times5 mesh structure, with a pitch of 200mum. The power consumption is 80mW at 0.9V.
This paper presents an inductive-loaded standing-wave clock oscillator. By coupling the oscillators into mesh structure, multi-ten GHz uniform-phase/amplitude global clocks can be distributed over a whole chip. In the mesh structure, finer grid can be employed than the conventional standing-wave technique, and it makes the depth of clock tree very shallow. We designed and fabricated a 17.2GHz oscillator...
A 3D integration custom stack system utilizing a local wireless interconnect (LWI) and a global wireless interconnect (GWI) is proposed. The LWI transfers Gb/s pulses using resonant coupling of spiral inductors with low-power dissipation of several mW. The GWI transfers global clocks and data on a 20 GHz signal using on-chip antennas.
