Problems solved by technology

Oscillations can stop for a certain amount of time and resume later, or in the worst case, oscillations can be lost entirely and may not recover on their own
Therefore, the display of information in the electronic shelf label may be disturbed by EMI, or the label may be disturbed to stop working

Abstract

An oscillator circuit arrangement comprises an inverter having input and output terminals (XIN, XOUT) that are to be connected to a crystal device. An automatic gain control device (AGC) controls a current source (MP2) that supplies current to the inverter. First and second diode devices (MND2, MND3) 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.

Description

technical field [0001] The present disclosure relates to an oscillator circuit arrangement for low power applications. In particular, the present disclosure relates to an oscillator circuit arrangement comprising an inverter to be connected to a crystal device and an automatic gain control device controlling a supply current to the inverter. The present disclosure also relates to the application of the oscillator circuit device in electronic tags. Background technique [0002] Oscillators are widely used to provide clock signals to control the operation of electronic devices. An oscillator can be implemented by an integrated circuit on a semiconductor chip with an external component such as a crystal to provide the time base and capacitors to provide the appropriate phase shift of the signal. [0003] Oscillators according to the Pierce architecture can be used in fields such as electronic tag or electronic paper applications where power consumption is critical. Electroni...
