The high-molecular resin is corroded by hot concentrated nitric acid (98%) or concentrated sulfuric acid to become low-molecular compounds that are easily soluble in acetone. Under the action of ultra
The MCU’s main power supply pairs DVCC and DVSS supply power to the digital and analog blocks, respectively. The recommended bypass and decoupling capacitors are4.7μF to 10μF and 0.1μF, respectively,
This course "From System Level to Circuit Level" focuses on the theme of weak signal processing circuits. The content is organized from system level to circuit level. The teaching goal of system level
