A PULSE-BASED NON-CARRIER 7.5GHz UWB TRANSCEIVER SoC WITH ON-CHIP ADC

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 single-band (7.5GHz), pulse-based non-carrier architecture, which consists of low-noise amplifier (LNA), correlator, integrator, pulse generator, power switches, timing controller and on-chip ADC. The SoC features BPSK modulation, Gaussian pulsing, and a global switching technique for power reduction. The average power consumption of the transceiver (no ADC) is 6mW only. The SoC is designed in commercial 0.18mum CMOS technology
