Instantaneous frequency measurement for IR-UWB signal in CMOS 130 nm

Abstract

For about a decade, Ultra-WideBand applications demonstrated its interest for radio and imaging applications in the [3.1–4.9 GHz] frequency band. In order to carry out such applications in other frequency domains, the instantaneous frequency of the impulse signal is commonly used. This paper describes the design of an Instantaneous Frequency Measurement system in order to show its feasibility for Ultra-WideBand impulse radio radar and imaging applications. The integrated part of the system is constituted of a full-wave rectifier, a delay cell and an analog multiplier. These devices were designed in CMOS 130 nm technology and consumes 95.6 mW for a supply voltage of 1.2V. The post-layout simulations are shown in comparison to theoretical Matlab simulations in order to validate the proposed technique.
