We propose a bio-inspired circuit performing pulse-density modulation with single-electron devices. The proposed circuit consists of three single-electron neuronal units, receiving the same input and are connected to a common output. The output is inhibitorily fedback to the three neuronal circuits through a capacitive coupling. The circuit performance was evaluated through Monte-Carlo based co...

A 2.4-GHz CMOS on-off keying (OOK) transmitter is developed for applications that require high data rate over 10Mbps in the area of wireless body area network (WBAN) and medical implant communication service (MICS). A novel analog pulse-shaping circuit for reducing power consumption and circuit complexity is employed for the OOK transmitter. Fabricated in 0.13μm CMOS, the transmitter core exclu...

An inhibitory network model that performs noise-shaping pulse-density modulation [1] was implemented with subthreshold analog MOS circuits, aiming at the development of ultralow-power Σ∆-type AD converters. Through circuit simulations, we evaluate the effects of the noise shaping produced by the network circuit. Keywords—VLSI, pulse density modulation, noise shaping, chaotic neural networks 1 M...

Design and implementation of a 10kV subnanosecond pulse generator using Trigatron type spark gap as a switch. Straightforward and compact trigger generator using pulse shaping network which produces a trigger pulse of subnanosecond rise time. A pulse power system requires delivering a high voltage, high coulomb in short rise time. This is achieved by using pulse shaping network comprises of par...

The speed of serial interface through a backplane channel suffers severe ISI (Inter Symbol Interference) caused by the limited bandwidth of the channel. In order to overcome the bandwidth limit, a pulse shaping circuit or an adaptive equalizer is used. This paper presents the comparison between two approaches. Prototype chip is designed for 10Gbps serial data communication through a 34-inch tra...

We designed subthreshold analog MOS circuits implementing an inhibitory network model that performs noise-shaping pulse-density modulation with noisy neural elements. Our aim is to develop a possible ultralow-power delta-sigma-type one-bit analog-to-digital converter. Through circuit simulations we confirmed that the signal-to-noise ratio of the network was improved by 7.9 dB compared with that...
