SQUARE TRIANGLE VCO


Posted on Feb 4, 2014

With DC control voltage of 5 mV to 5 V, circuit controls frequency of both square and triangle outputs with good linearity. Peak value of triangle output is precisely set at 2. 44 V and 0 V by reference voltages at noninverting inputs of comparators. Comparator A2 drives load for low outputs, while comparator A1 drives load when output is high. Arti
