Abstract
A mm-wave BiCMOS back-end metallization switched
delay line frequency agile filter is presented. Miniaturization of
the delay lines is achieved by using slow-wave propagation modes
on shielded CPWs, with a standard BiCMOS process transistors
used as on-chip switching elements. A first-order filter is
presented, with simulation results indicating one transmission
band at 40.4 GHz of 22.8 % relative bandwidth and insertion loss
of –12.25 dB, with the other transmission band at
47.55 GHz with a 23.79 % relative bandwidth and insertion loss
of –13.66 dB. Both bands feature below -15 dB input reflection
loss. The paper further establishes the potential for shielded
CPW transmission lines for the design of complex passive devices
on the back-end metallization of various semiconductor
technologies.
