ABSTRACT:
Nano-scale CMOS technologies have enabled the cost effective implementation of many millimeter wave (mm-wave) frequency applications such as wireless HDMI, automotive radar and passive imaging systems. However, due to the limitations of the existing passive/active device modeling, together with the parasitic and coupling effects at very high frequencies, multiple silicon iterations are often needed to predict the performance of wireless transceiver circuits. Furthermore, the ultra-high frequency operation often invalidates many programmable methods, leading to transceiver front-end circuits hard to adjust for various performance requirements and compensate the ever increasing process variations. We investigate circuit techniques and design methodologies to enhance the robustness of mm-wave ICs. In this talk, the design of a 77GHz CMOS receiver suitable for automotive radar will firstly be introduced. Then the configurable Coplanar Waveguide (CPW) based sub-nH inductor structures, together with a unique ESD protection method for mm-wave front-end will be discussed toward robust implementation of mm-wave ICs.
