Abstract
An oscillator circuit arrangement comprises an inverter having input and output terminals that are to be connected to a crystal device. An automatic gain control device controls a current source that supplies current to the inverter. First and second diode devices having different orientation are connected between the input and the output of the inverter. The oscillator consumes low power and has a fast recovery time after an electromagnetic interference event. The oscillator can be used in electronic labels.
