Chapter 3 of the book "Operational Amplifier Parameter Analysis and LTspice Application Simulation" is about special amplifiers, including four types of special amplifiers: instrumentation amplifiers,...
1. Transistor
The transistor is a current-controlled device. Its main function is to amplify weak signals. It has low input impedance. For example, a very small current Ib is given to the base b, an...
There are generally two ways to increase the transmission rate of wireless transmission. One is to increase the spectrum utilization rate, and the other is to increase the spectrum bandwidth. In wirel...

1. Background
I have done a project on STM32 low-power signal acquisition before, using the STM32L031 microcontroller. The project requirements are as follows:
The device is powered by a battery, dete...
