Title:
CURRENT STABILIZING CIRCUIT AND CURRENT STABILIZING METHOD THEREFOR, INTEGRATED CIRCUIT, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/226969
Kind Code:
A1
Abstract:
A current stabilizing circuit, a current stabilizing method, an integrated circuit, and an electronic device. The current stabilizing circuit comprises a current adjusting circuit (200) and a driving circuit (100); the driving circuit (100) is configured to output a driving current (Iq); the current adjusting circuit (200) is configured to, according to the driving current (Iq) and a load current (IL), compensate the driving current (Iq), so that the driving current (Iq) is stabilized within a preset current range. After a load (L) changes, the driving current (Iq) outputted by the driving circuit (100) also changes accordingly; in this case, the current adjusting circuit (200) can quickly adjust the driving circuit (100), that is, according to the driving current (Iq) obtained from the driving circuit (100) and the load current (IL), the driving current (Iq) is quickly compensated, so that the compensated driving current (Iq) is stabilized within the preset current range. Therefore, current stabilization with respect to the load (L) change can be realized.
