Low power and small volume are always the most important issues in the internal module of a wireless implantable neural recording system. In this paper, a BPSK demodulator base on digital-analog hybrid COSTAS Loop is presented. A digital multiplier replacing the analog multiplier is presented specially to achieve lower power consumption in the proposed circuit. The proposed BPSK demodulator features...
Low power, small volume and high acquisition precision are always important in the internal module of wireless implantable neural recording system. This paper describes the design and implementation of a new successive approximation (SAR) ADC to meet the unique requirements of wireless implantable neural recording system. In the designed new ADC, a fully differential structure is used to avoid the...
There is a growing demand of high-precision and low-power ICs for physiological signal acquisitions. One of the crucial functional blocks for such ICs is the analogue front-end circuit. In this paper we presented a compact analogue front-end circuit with adjustable gains that is elaborated for various physiological signal acquisitions. The circuit we have developed consists of a gain programmable...
During technology development, the study of ultra low-k (ULK) TDDB is important for assuring robust reliability. As the technology advances, several critical ULK TDDB issues were faced for the first time and needed to be addressed. First, the increase of ULK leakage current noise level induced by soft breakdown during stress was observed. Second, it was found that ULK had lower field acceleration...
According to mini-LVDS specification, the minimum setup and hold time of the receiver are analyzed. The design of a receiver basing on Chartered-Semiconductor 0.35 mum CMOS process is presented, and a simple simulation method is proposed, which can effectively evaluate performance of the receiver. The simulation results show that the setup and hold time of the receiver are all less than 0.8 ns. The...
A fully integrated receiver in a 0.13 mum CMOS technology including on-chip power amplifier (PA) for digital cordless telephone standards is presented. The implemented frequency synthesizer shows robustness against PA coupling, excellent phase noise performance and fast settling time. The frequency tuned LNA and IF-filter is designed to cover the frequency bands from 1.8 GHz to 2.5 GHz. The fully...
A fully integrated transceiver in a 0.13 mum CMOS technology including on-chip power amplifier (PA) for digital cordless telephone standards is presented. The PA exhibits an output power of POUT = 26 dBm. The implemented frequency synthesizer shows robustness against PA coupling, excellent phase noise performance and fast settling time. The fully integrated receiver deploys a low intermediate frequency...
During the development and qualification of a 300mm low-k/Cu back end of line (BEOL) technology, the long-term reliability of such interconnects including low-k time-dependent dielectric breakdown (TDDB), Cu electromigration (EM), Cu stress migration (SM), and Cu/low-k thermal behavior are rapidly becoming one of the most critical challenges. In this paper, a comprehensive reliability evaluation for...
The first generation of C-RAM memory is designed to greatly exceed (in density, write speed, endurance) the existing non-volatile memory solutions for space and to close the gap that exists between system requirements and availability. Based on the success of the 64kb C-RAM program, a 4Mb C-RAM prototype has been designed and fabricated in 0.25 mum radiation-hardened CMOS. In this paper we present...
