Title:
SAFE-INPUT DYNAMIC SAMPLING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/091070
Kind Code:
A1
Abstract:
A safe-input dynamic sampling circuit, comprising: a rectifier circuit (10), which converts an input signal into a direct current signal; a voltage regulator circuit (11), which is connected to the rectifier circuit (10) and which controls the voltage amplitude of the direct current signal; a sampling circuit (12), which comprises a first input terminal (121), a second input terminal (122), and a sampling terminal (123), the first input terminal (121) receiving an input signal, and the second input terminal (122) receiving a sampling control signal, and collecting from the sampling terminal (123) a direct current signal that corresponds to the first input terminal (121), thereby reducing the probability of a signal of a dangerous side being misjudged.
