Abstract
Integrated circuits such as multi-channel transceivers may share oscillators having loop inductors. To minimize the driving distance from the shared oscillators to the transceiver modules, the loop inductor may be equipped with an additional sense port diametrically opposite to the drive port. An oscillator drive core may be coupled to the drive port to provide an oscillating signal at the drive and sense ports. The oscillating signals can be converted into digital clock signals by way of a differential amplifier. Three-loop inductor designs and/or multi-winding inductor designs may be preferred for minimizing parasitic effects of the added sense port.
