Source: InternetPublisher:smallembedded Keywords: Detection circuit Updated: 2024/09/05
As shown in the figure, it is a wide-band linear detection circuit with a bandwidth of 10MHz. This circuit is a wide-band linear detection circuit with a bandwidth of 10MHz used in measuring instruments such as millivoltmeters. The operational amplifier uses a wide-band μPC53, and its output is amplified by a differential amplifier composed of a transistor 2SC384. The circuit uses a germanium diode as a detection diode and connects it to a negative feedback circuit. The differential circuit increases the power supply voltage.
