Precision voice control sensor integrated control device

Abstract

The invention discloses a precise voice control sensor integrated control device. A charge control / output protection and output compensation controller is used for detecting voltage of a signal output end, detecting gate charge of an MOS (metal oxide semiconductor) transistor M1 and gate charge of an MOS transistor M2 and detecting voltage of a signal input end, signal output is compensated through an intelligent linear switch, and voltage of signal output is enabled to be within a set voltage range; or output is enabled to be zero or a switch K1 and / or a switch K2 is closed. The precise voice control sensor integrated control device has extremely high noise resistance, extremely wide voice rang, tiny distortion, extremely small size and extremely few ports; full-domain signal input is adopted, the variable-frequency intelligent linear switch is introduced in, the innovative charge algorithm control technique is adopted for charge control, output protection and output compensation control, further diodes, resistors and JFETs (junction field-effect transistors) adopted by the device are all special semiconductor processes, integration of a system is optimized fundamentally, and tiny size can be realized.

Description

technical field [0001] The invention relates to an integrated control device for a sound-activated sensor, in particular to an integrated control device for an extremely small and precise acoustic-activated sensor. Background technique [0002] searched, such as figure 1 Shown is a widely used impedance conversion and filter network application circuit in the prior art. Although the circuit is small in size, it cannot realize alternating signal transmission, has extremely poor antistatic ability, and low response. figure 2 It is the second one. The second circuit is complex and requires complex impedance matching conversion, control circuits and filter networks. The impedance conversion capability is poor, the response is lower, and the use of discrete components cannot be integrated, resulting in a very large size. Both circuits use commonly used discrete devices, which perform poorly in terms of reliability, antistatic ability, and consistency. Contents of the inventio...
