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

Abstract

During the last decade, Ultra-WideBand applications showed many interests for radio and imaging applications in the [3.1-4.9 GHz] frequency band. To realize 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 the feasibility to use it 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 was designed in CMOS 130 nm technology and the post-layout simulation are shown in comparison to theoretical Matlab simulations.
