Abstract

The invention discloses a center amplifier. The center amplifier comprises a multi-stage amplification circuit, a rectification filter circuit, a threshold chopper circuit and an amplitude limiting and comparison circuit, which are integrated on one circuit board. The multi-stage amplification circuit has two paths of output, wherein one path is connected with a bandwidth filter, and the other path is connected with the rectification filter circuit. The output end of the rectification filter circuit is connected with the input end of the threshold chopper circuit. The output end of the threshold chopper circuit is connected with the input end of the amplitude limiting and comparison circuit. According to the center amplifier, the multi-stage amplification circuit, the rectification filter circuit, the threshold chopper circuit and the amplitude limiting and comparison circuit are integrated on one circuit board, and target mark signals are formed in forms of high and low levels, and are transmitted to subsequent components such as electronic parts. The center amplifier outputs a plurality of independent signals such as process output signals, synchronous output signals, analogue output signals and pulse output signals for other units to use, and is high in output stability, low in power consumption, small in size and high in reliability, and the signals are independent.

Description

technical field [0001] The invention belongs to the field of electronic components, in particular to a central amplifier. Background technique [0002] The components of the existing central amplifier are assembled with discrete components, which are bulky, heavy, long production cycle, poor shielding, unsatisfactory in stability and reliability, and cannot meet the requirements of national defense equipment upgrades and high reliability. Similar products are available, therefore, a central amplifier with a high degree of integration and high reliability is urgently needed. Contents of the invention [0003] The purpose of the present invention is to provide a central amplifier to solve the existing problems of independent assembly of the central amplifier, such as large volume and heavy weight. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a central amplifier, including a multi-stage amplifier circuit, a rectif...
