Abstract
In an inverter oscillation circuit an output terminalof an inverterwith its input and output interconnected via a high resistance Ris grounded via a series connection of a capacitor Cand parallel tuning circuit composed of a capacitor Cand an inductor Lconnected in parallel, and the connection point of this series connection is grounded via a parallel circuit of diodes Dand Dconnected in opposite polarities. The connection point of the series connection is connected to an input terminalof the invertervia series-connected capacitors Cand C, and the connection point of this series connection is grounded via a piezoelectric vibrator Xtal and a frequency adjusting capacitor C. The inverter oscillation circuit is configured to provide its output via a series circuit composed of a resistor Rand a capacitor C
