Abstract: | A novel high performance transconductor-based mutually coupled circuit topology is presented, employing four active devices
(six, if differential-output devices are not available) and only grounded passive elements. The primary and secondary self-inductances
and the mutual inductance can be controlled independently. Being constructed with integrator and transconductor blocks, the
circuit offers excellent sensitivity, stability and high frequency performances. The current-conveyor-based implementation
is also presented to avail comparison with previous counterparts. Via measurements and simulations, theoretical predictions
are verified and the comparisons are performed. As an RF application example, a tuned amplifier is built and simulated. |
