D15.11Using a MOSFET biased to operate at gm = 5 mA/V, design a Colpitts oscillator to operate at ω0 = 106 rad/s. Use C1 = 0.01 µF and assume that the coil available has a Q of 100 (this can be represented by a resistance in parallel with C1 given by Q/ω0C1). Also assume that there is a load resistance at the collector of 100 kΩ and that for the MOSFET, ro = 100 kΩ. Find C2 and L. 0.42 µF; 102 µH (a somewhat smaller C2 would be used to allow oscillations to grow in amplitude)
