This paper presents a dynamic zoom analog-to-digital converter for use in low-bandwidth (<1 kHz) instrumentation applications. It employs a high-speed asynchronous successive approximation register (SAR) ADC that dynamically updates the references of a fully differential Δ Σ ADC. Compared to previous zoom ADCs,...

This paper describes a high-resolution energy-efficient CMOS temperature sensor, intended for the temperature compensation of MEMS/quartz frequency references. The sensor is based on silicided poly-silicon thermistors, which are embedded in a Wien-bridge RC filter. When driven at a fixed frequency, the filter exhibits a temperature-dependent...

One of the most striking challenges that radar designers have to deal with, when developing new doppler systems, is to overcome the difficulty of working with ambiguous velocities. Even using high PRF’s, target’s velocities become ambiguous because wavelengths are getting shorter. This article tries to depict an idea of becoming unambiguous in...
