A 100Mb/s 1.37mW impulse-radio ultra-wideband (IR-UWB) receiver with Costas-loop based frequency and phase synchronization scheme is developed in 65nm CMOS. This is the first analog-domain plesiochronous solution for IR-UWB communication in DC-960MHz band without the necessity of traditional analog-to-digital converter (ADC) and digital baseband for signal processing, thereby the receiver achieves the lowest energy of 13.7pJ/bit in state-of-the-art plesiochronous IR-UWB communication.
