This paper presents the design of a low-power single-full-band (3.1-10.6 GHz) noncarrier impulse-radio ultra-wideband (UWB) transmitter (TX) implemented in a commercial 0.18-μm CMOS technology. This UWB TX features fifth-order Gaussian derivative pulse shaping, integrated binary phase-shift keying modulation and 2.5-kV whole-chip electrostatic(More)
In this paper, a single-chip pulse-based, non-carrier, full-band, low power ultra wideband (UWB) transceiver system-on-a-chip (SoC) for high data rate wireless video/audio/multimedia streaming applications is presented. This UWB SoC features a single full-band (7.5GHz bandwidth from 3.1GHz to 10.6GHz), pulse-based non-carrier architecture to achieve high(More)
—This paper reports a new nanocrystal quantum-dot (NC-QD)-based tunable on-chip electrostatic discharge (ESD) protection mechanism and structures. Experiments validated the pro-grammable ESD protection concept. Prototype structures achieved an adjustable ESD triggering voltage range of 2.5 V, very fast response to ESD transients of rising time t r ∼ 100 ps(More)
This paper reports a new nano crystal quantum dots (NC-QD) tunable on-chip electrostatic discharge (ESD) protection mechanism and structures. Experiments validated the programmable ESD protection concept. Prototype structures achieved an adjustable ESD triggering voltage range of 2.5V, very fast ESD response of ~100pS, ESD protection density of(More)
In this paper, a single-chip pulse-based, non-carrier, high throughput, low power ultra wideband (UWB) transceiver system-on-a-chip (SoC) with on-chip analog-to-digital converter (ADC) for high payload wireless video/audio/multimedia streaming applications is presented. To achieve high throughput (>100Mbps) and high simplicity, the UWB SoC adopts(More)
Analog-to-digital conversion plays an essential role in all kinds of electronics systems, including signal processing, communications and storage. In particular, interpolated flash ADC has been widely used in high-speed systems requiring very high sampling speed. Obviously, practical ADC design is very challenging, which has been dominated by experiences(More)
Actinidia kolomikta (Rupr. & Maxim.) Maxim. leaves showed dramatic colour changes during plant growth phases, and we studied structure and optical properties of variegated leaves. Leaf surface cells were smooth, and there were no surface appendages (wax or trichomes) observed in variegated leaves. Palisade tissue cells in white and pink leaves were looser(More)
