AI Technical Summary
Existing slope detection circuits have shortcomings in terms of high-speed detection capability, low-power design, and chip integration. In particular, they have low detection accuracy and high power consumption in high-frequency detection scenarios, which cannot meet the needs of high-speed bus chips and low-power electronic systems.
A closed-loop linkage design is adopted, consisting of a signal detection circuit, a comparison feedback circuit, and a charge discharge circuit. The charge discharge circuit quickly discharges the charge of the detection node after the detection signal is triggered, ensuring that the voltage of the detection node quickly returns to the initial state and avoiding voltage baseline drift and detection threshold shift caused by charge accumulation.
It improves detection accuracy and stability, reduces power consumption, simplifies circuit structure and reduces hardware integration costs, and is suitable for high-speed signal detection and low-power electronic systems.
