MILLIMETRE WAVE BANDPASS FILTER ON CMOS

摘要

Q of resonant elements formed over lossy substrates such as in a CMOS process is improved by forming the ground plane of the resonant element immediately over a high impedance layer to reduce cross coupling and eddy currents. A new type of meandering hairpin resonator configuration is also introduced providing, for example, for 4th order cross coupled filters of high selectivity and compact layout.
