摘要:
A method of operating an image sensor includes: generating a pixel signal according to intensity of incident light; and generating a digital pixel signal based on a comparison between the pixel signal and at least one reference current. Accordingly, a current output from a 1T pixel in the image sensor is sensed such that the influence of noise is reduced and a pixel signal is sensed more precisely.

An interface capable of suppressing parasitic capacitance effects includes an array of switches switched in response to a switching signal. The interface suppresses effects of parasitic capacitance included in a bus, which transmits a reset signal and an image signal output from an image sensor. The suppressed parasitic capacitance effects suppress distortion of a digital image signal.

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.
