A high-gain amplifier that amplifies weak magnetic flux by 1000 times

A high-gain amplifier that amplifies weak magnetic flux by 1000 times If the AC magnetic field is coupled with the pickup coil, it will induce voltage, and the DC magnetic field will also induce voltage due to the change of the magnetic field. Using this principle, it is possible to detect whether there is a magn

Building a Digitally Programmable Gain Amplifier with Negative Time Constant

A digitally programmable gain amplifier (DPGA) amplifies or attenuates an analog signal to maximize the dynamic range of an analog-to-digital converter (ADC). Most monolithic DPGAs use a multiplexed multiplying digital-to-analog converter (DAC) in the feedback loop of an op amp, such as the Maxim LTC6910 and National

Time-Varying Gain Amplifier

In short, the so-called time-varying gain amplifier is an amplifier whose gain is a function of time. Since in the ground penetrating radar system, time actually corresponds to the distance of the target from the antenna, from this perspective, in the radar system, it can be called a distance gain amplifier. Its me
