Many bio-chemistry information on the frequency characteristic can be revealed at ~GHz microwave frequencies. As shown in the figure below, the dielectric property of salt water has a huge transition in the frequency range of 1GHz to 10GHz. In such applications, the fully-integrated microwave receivers with a build-in frequency generation that can operate over a very wide frequency range (over 3 decades) are one of the most critical components of such systems. Standard CMOS technologies are used to reduce the cost of manufacturing and system integration, enabling the point-of-care diagnosis. However, the lossy and leaky substrate in CMOS process makes such broadband design very challenging.
In this PhD. project, the key design challenges of a CMOS microwave receiver covering a frequency range from a few tens of MHz up to 40GHz will be studied, and the prototype CMOS ICs will be developed. The resulting IC prototypes will also be tested in the real imaging and bio-sensing applications.
