Design of a Wide-Bandwidth Magnetic Field Sensor

The combination of Hall sensors and coils can be a practical solution for obtaining a CMOS-compatible contactless current sensor with high bandwidth. A current sensitivity of 1mV/A is achieved by the Hall sensors, and the coils have a current sensitivity of about 8mV/A?µs-1. The current sensitivity is influenced by the actual die position inside...

ADPLL Design for WiMAX

The frequency synthesizer, which functions as a local oscillator, is a critical block in the transceiver. It needs to meet very stringent specifications and consume as less power as possible. Design of a traditional charge-pump PLL as the frequency synthesizer in the advanced CMOS technologies in the transceiver of advanced communication systems...

Signal Up-conversion for Integrated Radar Systems

Frequency up-conversion is an integral part of the (sub)mm wave integrated radar system that is currently developed at the TUDelft in the context of the MEMPIS program. The proposed up-converter IC allows the necessary signal modulation for the radar to be generated at a relative low frequency, after up-conversion to W-band takes place. In our...
