imec - Design of Crystal-less Transceiver

At imec, circuits4IoT

In implantable/wearable application, a need for complete monolithic RF/ sensor nodes is arising from reducing size and cost. However, crystal oscillator as a clock reference is inevitable, which hinders full chip integration. This project focuses on designing the crystal-less transceiver for low-cost and small size radio.

 

Project Description

Crystal oscillators become one of the most critical component in wireless communication. However, it limits the size and cost reduction of the overall wireless module. Many applications, e.g., implantable devices, need a complete integration for small-size and cost-efficiency RF transceiver, which cannot afford to employ a bulky external crystal. To realize a miniaturized and low-cost transceiver, the crystal-less transceiver design will be investigated in this project. A low-jitter and low-frequency CMOS oscillator can substitute for the crystal oscillator.

 

In this project, three main goals will be implemented in advanced CMOS technology:

  • Design for crystal-less receiver with high sensitivity
  • CMOS reference clock design
  • Overall Transceiver design and its verification
