Title:
NEGATIVE BOOTSTRAP CIRCUIT, MICRO-ENERGY DEVICE, AND CONTROL METHOD FOR NEGATIVE BOOTSTRAP CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/082135
Kind Code:
A1
Abstract:
A negative bootstrap circuit, a micro-energy device, and a control method for a negative bootstrap circuit. A gate electrode of a first switch tube (Q1) is connected to a first control end of the negative bootstrap circuit; a gate electrode of a third switch tube (Q3) and a gate electrode of a fourth switch tube (Q4) are jointly connected to a second control end of the negative bootstrap circuit; a gate electrode of a fifth switch tube (Q5) and a gate electrode of a sixth switch tube (Q6) are jointly connected to a third control end of the negative bootstrap circuit; a positive electrode of a first energy storage assembly (11) is connected to a drain electrode of the first switch tube (Q1) and a power source end of a radio frequency assembly (10); a source electrode of the first switch tube (Q1) is connected to a drain electrode of the third switch tube (Q3), a drain electrode of the fifth switch tube (Q5) and a positive electrode of a third energy storage assembly (13); a source electrode of the third switch tube (Q3) is connected to a source electrode of the fourth switch tube (Q4) and a positive electrode of a second energy storage assembly (12); and a source electrode of the fifth switch tube (Q5), a source electrode of the sixth switch tube (Q6), a negative electrode of the second energy storage assembly (12) and a grounding end of the radio frequency assembly (10) are jointly connected to a signal ground, thereby preventing the bootstrap circuit from malfunction.
