1. An oscillator circuit of the type including complementary metal-oxide-semiconductor;

  • field-effect-transistors (MOSFET), comprising;

    a source of potential having at least a first level of potential and a second level of potential, a first, enhancement mode MOSFET having source, drain, gate, and substrate electrodes, a second, enhancement mode MOSFET having source, drain, gate, and substrate electrodes, said substrate electrode of each MOSFET being connected to said source electrode of said same MOSFET, an output terminal, said source electrode of said first MOSFET being connected to said first level, an output capacitor participating in the establishment of a bias potential and having a first end and a second end and being connected to said second level by said second end, said drain electrodes of said first and second MOSFETS being interconnected at a first junction with said first end of said output capacitor for providing a charging path for said output capacitor through said first MOSFET and for providing a discharging path for said output capacitor through said second MOSFET, said gate electrodes being interconnected and forming a second junction, an input capacitor being connected between said second junction and said second level for participating in the establishment of a bias potential for said drain electrodes, said source electrode of said second MOSFET being connected to said second level, a crystal for setting the frequency of oscillation is connected between said first and second junctions, and a starting resistor is connected between said first and second junctions for ensuring that the interconnected first and second MOSFETS are not initially latched in a static state.
