Abstract
A known crystal oscillator circuit is modified to improve the starting of oscillations therein when a low supply voltage is employed. The oscillator circuit includes two complementary field effect transistors connected in a known manner to each other and a frequency determining circuit including a crystal. The modification includes a first additional field effect transistor having its drain-source path connected in parallel with the drain-source path of one of the oscillator field effect transistors or a second additional field effect transistor having its drain-source path connected in parallel with the drain-source path of the other of the oscillators field effect transistors. The first and second additional field effect transistors are of the same conductivity type as the oscillator field effect transistor it is in parallel with.
