ABSTRACT
Peak responding MCDs are classified as (1) peak detecting MCD and (2) peak sampling MCD. A short pulse/saw tooth waveform, whose time period T is (1) proportional to one voltage V2 and (2) inversely proportional to another voltage V1, is generated. The third input voltage V3 is integrated during this time period T. The peak value of the integrated output is proportional to https://www.w3.org/1998/Math/MathML"> V 2 V 3 V 1 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003362968/84470805-1cf0-4c82-9123-c2aee45613c9/content/eqa_5.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> . This is called a double single slope peak responding MCD. A square wave/triangular waveform, whose time period T is (1) proportional to one voltage V2 and (2) inversely proportional to another voltage V1, is generated. The third input voltage V3 is integrated during this time period T. The peak value of the integrated output is proportional to https://www.w3.org/1998/Math/MathML"> V 2 V 3 V 1 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003362968/84470805-1cf0-4c82-9123-c2aee45613c9/content/eqa_6.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> . This is called a double dual slope peak responding MCD. A rectangular waveform, whose (1) time period T is inversely proportional to the first input voltage V1 and (2) whose OFF time is proportional to a second input voltage V2, is generated. The third input voltage V3 is integrated during this OFF time. The peak value of the integrated output is proportional to https://www.w3.org/1998/Math/MathML"> V 2 V 3 V 1 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003362968/84470805-1cf0-4c82-9123-c2aee45613c9/content/eqa_7.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> . This is called a pulse width integrated peak responding MCD.
At the output of a peak responding MCD, if a peak detector is used, it is called a peak detecting MCD, and if sample and hold is used, it is called a peak sampling MCD. The peak responding MCDs of both peak detecting MCDs and peak sampling MCDs using analogue switches are described in this chapter.
