Abstract
In a piezoelectric oscillator a non-inverted output terminal () of an ECL circuit () is grounded via a capacitor (C) and is connected to a non-inverting input terminal () of the ECL circuit () via a series connection of capacitors (C) and (C). The non-inverting input () is connected via a resistor Rto an inverting input terminal () of the ECL circuit () and is grounded via a capacitor (C). The connection point of the series connection of the capacitors (C) and (C) is grounded via a crystal oscillator (X'tal) and a frequency control capacitor (C). The output from the ECL circuit () is provided at its inverted output terminal
