Title:
OSCILLATION CIRCUIT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/248411
Kind Code:
A1
Abstract:
An oscillation circuit (1) according to this invention comprises a Pierce circuit (2) and a Colpitts circuit (3) that share an oscillator (X1) and the input part of amplifiers (A1, A2). Switches (SW1, SW2) connected between the output parts of the respective amplifiers (A1, A2) of the Pierce circuit (2) and Colpitts circuit and the ground are controlled to output an oscillation signal of the Pierce circuit (2) during oscillation startup and to output an oscillation signal of the Colpitts circuit (3) during steady oscillation. An oscillation circuit that enables both high-speed startup and low current consumption can be provided.
