Abstract
A cross-coupled complementary balanced voltage-controlled oscillator and a method for operating same. The oscillator comprises an electro-mechanical resonator, and an oscillator core. The oscillator core comprises capacitvely cross-coupled complementary inverters and a resistor network. The oscillator may comprise a frequency tuning network having inductors for increasing the tuning range. The capacitance inhibit the inverters from latching to a static direct current state. The resistor network forms a high pass filter with the capacitance to inhibit relaxation oscillations. The method comprises enabling the resistor network to form a high pass filter and starting balanced oscillations in the oscillator, the capacitance of the high pass filter for inhibiting latching, and the high pass filter for inhibiting relaxation oscillations. The method may comprise tuning the frequency by varying the capacitance of the oscillator.
