Abstract
Isolators for high frequency signals transmitted between two circuits configured to operate at different voltage domains are provided. The isolators may include resonators capable of operating at high frequencies with high bandwidth, high transfer efficiency, high isolation rating, and a small substrate footprint. In some embodiments, the isolators may operate at a frequency not less than 30 GHz, not less than 60 GHz, or between 20 GHz and 200 GHz, including any value or range of values within such range. The isolators may include isolator components galvanically isolated from and capacitively coupled to each other. The sizes and shapes of the isolator components may be configured to control the values of equivalent inductances and capacitances of the isolators to facilitate resonance in operation. The isolators are compatible to different fabrication processes including, for example, micro-fabrication and PCB manufacture processes.
