Pulse Position-Responding MCDs

Pulse position peak-detecting MCDs, pulse position-sampled MCDs and pulse-width integrated peak-sampling MCDs are called pulse position-responding MCDs and discussed in this chapter.

A sawtooth wave of period T whose peak value is proportional to one input voltage (V₃) is connected to a peak detector during a time δ_T, which is proportional to another input voltage (V₂). The time period T of this sawtooth wave is proportional to one input voltage (V₁). The peak detector output is proportional to V₂ V₃ /V₁ . δ_T is obtained from T and δ_T < T. This is called pulse position peak-detecting MCD.

A sawtooth wave of period T whose (i) time period T is proportional to one input voltage (V₁) and (ii) peak value is proportional to one input voltage (V₃) is sampled by a sampling pulse whose position over the period T is proportional to another input voltage (V₂). The sampled output is proportional to V₂ V₃ /V₁ . This is called a pulse position-sampled MCD.
