Electric field detector based on CMOS6 NOT gate

Abstract

The invention discloses an electric field detector based on a CMOS6 NOT gate, which comprises an electrostatic detector and an audio electric field detector. The electrostatic detector and the audio electric field detector detect a first NOT gate of a CMOS6 NOT gate integrated circuit as an electric field, and the rest five NOT gates are inverting amplifiers with stable neutral-point potential; and an input end of the first NOT gate is connected with a probe. A second NOT gate of the electrostatic detector is used for pre-amplification, a third NOT gate and a fourth NOT gate of the electrostatic detector are connected in parallel and used as output drive, and a fifth NOT gate and a sixth NOT gate of the electrostatic detector are connected in parallel and matched with resistors with the same resistance value to form a phase inverter of which gain is 1; a second NOT gate, a third NOT gate and a fourth NOT gate of the audio electric field detector form an inverting amplifier of which gain is infinite, are matched with a fourth resistance negative feedback stabilizing DC working point, and simultaneously form a band-pass amplifier with a second capacitor and a third capacitor together; and a fifth NOT gate and a sixth NOT gate of the audio electric field detector are connected in parallel and output audio current to an earphone for diagnosing during detection through a stopping electrolytic capacitor. The electric field detector can be used for detecting sunken cords and seepage, and has the advantages of low voltage, low power consumption and small volume.

Description

technical field [0001] The invention relates to an electric field detection device, in particular to the detection of embedded wires and leakage by integrated circuit amplifier electronic circuits. Background technique [0002] The strong and weak electricity that modern people cannot do without for a moment originally originated from the discovery of static electricity, but the development and application of static electricity today is not as fast as the power electronics industry. Although there are static activities everywhere around us: wearing rubber shoes or walking on insulated floors, picking up transparent plastic packaging boxes, rubbing against insulators, etc., we can only touch metal objects and get numb or turn off the lights in winter and take off chemical fibers You will know that there is static electricity only when you see a little spark when you are sorting clothes. This is because we do not have simple and easy-to-obtain electrostatic detection instrume...

In other words, there is still a lack of components or ICs with small size, low voltage and low power consumption, which are designed to flexibly design and construct pocket-sized instruments or devices based on static electricity or electric fields, to discover or utilize the ubiquitous static electricity or electric fields around us.
