Channel noise scan (CNS) approach is proposed in this paper to efficiently analyse the potential VR-signal coupling issue in the post-layout printed circuit board (PCB) check and the post-silicon debugging of the platform development. CNS is based on a new simulation methodology that includes the whole PCB with signals, voltage regulator (VR) networks, and the interaction. A frequency domain indicator...
This paper describes a PSRR enhancing method for the all-digital phase-locked loop (ADPLL) by utilizing a self-regulated gated ring-oscillator (SR-GRO) time-to-digital converter (TDC) and a voltage regulator just for a digitally-controlled oscillator (DCO). The SR-GRO employs a replica supply noise monitoring circuit which tracks supply noise and enables feed-forward error cancellation over broad...
In this paper, channel noise scan approach (CNS) is proposed to efficiently analyze the potential VR-signal coupling issue in the pre-silicon design and the post-silicon debug of the platform development. CNS is based on a new simulation methodology that includes the whole PCB with signals, voltage regulator (VR) networks, and the interaction between the two. The goal of this simulation methodology...
Floating-gate coupling occurs due to voltage changes in neighboring floating-gates. Coupling noise is difficult to overcome because of its non-linear property. We propose a coupling canceller for cancelling the coupling effect in multi-level cell NAND flash memory, and compare its performance with threshold detection. Simulation results show that the proposed floating-gate coupling canceller is an...
We review adaptive design techniques with particular emphasis on error-tolerant techniques. We compare and contrast traditional adaptive approaches with error-tolerant techniques and analyze the margins eliminated by each of them. We discuss the applications of the latter to on-chip communication and signal-processing. Finally, we focus on a specific example of an error-tolerant technique for general-purpose...
The paper presents a detailed study on the idle leakage reduction techniques on partially depleted silicon-on-insulator (PD-SOI) CMOS SRAM. The most promising leakage reduction techniques that have been proposed are introduced, analyzed and compared into 65 nm low-power PD-SOI technology, taking into account all the SOI specific effect. Especially, it is shown that the leakage reduction techniques...
A novel methodology for accurate and efficient static timing analysis is presented in this paper. The methodology is based on finding a frequency domain model for the gates which allows uniform treatment of the gates and interconnects. It is shown that despite the highly nonlinear overall gate model, a frequency domain model of the gate with the model parameters, gate moments, as functions of the...
Novel 3D stacked gate-all-around multichannel CMOS architectures were developed to propose low leakage solutions and new design opportunities for sub-32 nm nodes. Those architectures offer specific advantages compared to other planar or non planar CMOS devices. In particular, ultra-low IOFF (< 20 pA/mum) and high ION (> 2.2 mA/mum) were demonstrated. Moreover, those transistors do not suffer...
A novel compact coupled planar resonator (CCPR) based VCO (voltage controlled oscillator) using mode-coupling technique was developed in response to expensive high Ceramic and SAW resonators based signal source for wireless communications. One of the problems related to the conventional Ceramic/SAW based resonators (with high Q and low phase noise) is the challenge for integration in IC form. Instead...
The next generation of wireless communication is a ubiquitous radio system concept, providing wireless access from short-range to wide-area, with one single reconfigurable and adaptive system for all envisaged radio environments. This paper presents the design approach of RCO (reconfigurable concurrent oscillator) that simultaneously generates two or more signals of different frequencies that eliminate...
