Assignment:
There are two methods for designing the nonlinear triangle-to-sine converter.
1. Assume the maximum value of the sine wave is 1.2V (two diode potentials using the constant-voltage model of a silicon diode). Match the slope of the triangle wave vtri (θ) to that of the sine wave vs(θ) at = 0; this allows you to compute the maximal value Vtri of the triangle wave. Thenmatch the slope of the sine wave to that of the triangle wave multiplied by Rb/(Ra + Rb) when the triangle wave voltage reaches Vtri/2.This allows you to compute the ratio of the resistors.
2. Assume that the points of inflection of the piecewise-linear transfer characteristic occur at 29° (vs(θ) = 0.6V) and 73° (vs(θ) = 1.2V). Use the first point of inflection to determine the maximal value Vtri of the triangle wave and use the change in vs relative to the change in vtri between 29° and 73° to calculate the ratio of the resistors.
