This paper presents an 8-bit folding analog-digital converter (ADC) using switched capacitors. In this architecture, the conversion is achieved when the signal crosses a determined voltage level and at this time, a voltage value is added or subtracted from the analog input signal. The ADC proposed consists of eight identical stages that perform the conversion of one bit at a time. Each stage consists...
We present NanoRouter, a new router architecture implemented as a quantum-dot cellular automata (QCA). A router is a key component in the Internet core. It allows packets to be transferred in the Internet. QCA is a promising nanoscale technology where components have nano size, ultra-low power consumption and could have a clock rate on the terahertz range. In a bottom-up approach, we first describe...
This work aims to demonstrate an application of telemetry for monitoring process variables. The authors developed the prototype of a dedicated device capable of multiplexing, encoding and transmitting real-time data signals via amplitude-shift keying modulation to remotely located device(s). The prototype development is described in details, enabling the reproduction of the proposed telemetry system...
We demonstrate that quantum-dash mode-locked laser can perform all optical frequency down-conversion clock recovery up to 425 GHz. We measured 0.3 dB penalty on the optical recovered clock for 170 Gbit/s signal.
