Quadrature Oscillator: The following circuit is a high precision quadrature oscillator with active compensation. Vos = A.sin(@_t) and Voc=2.A.cos(@t) a) Label the op-amp terminals and the outputs, Vos and Voc b) Write the circuit equation for Voc in terms of the internal circuit component values. c) Write an expression that relates o to circuit component values. e) Write any circuit component constraint equations that are necessary to guarantee • that ||Voc|| = 2 ||Vos||- f) All capacitors must be 10 nF. Choose appropriate resistor values to make o, = 104 rad/sec. Voc R₁ www C₁ C₂ HH www R4 www 2 R₂ Vos R₂
