Applying trenched transient voltage suppressor (TVS) technology for distributed low pass filters |
摘要 |
An electronic circuit includes a filtering circuit implemented with a distributed inductor-and-capacitor (LC) network that includes metal oxide effect (MOS) trenches opened in a semiconductor substrate filled with dielectric material for functioning as capacitors for the distributed LC network. The electronic circuit further includes a transient voltage suppressing (TVS) circuit integrated with the filtering circuit that functions as a low pass filter wherein the TVS circuit includes a bipolar transistor triggered by a diode disposed in the semiconductor substrate. The distributed LC network further includes metal coils to function as inductors disposed on a top surface of the semiconductor electrically contacting the MOS trenches.
