Electrothermal integrator and audio frequency filter

摘要

An electrothermal integrator and audio frequency filter utilizing an electrothermal structure fabricated by way of a micro-machining process. An electrothermal structure is a structure in which there is thermal interaction between its electrical components. It is possible to implement an audio frequency filter by properly integrating electrothermal structures fabricated by micro-machining technology and electrical circuitry, because thermal response is generally slower than electrical response. It is possible to implement a variety of filters by way of forming a Gm-C integrator utilizing an electrothermal structure and using this basic block of Gm-C integrator in general circuitry to form filters.
