At the 2003 VLSI Technology Symposium, IBM and Infineon Technologies released a prototype of a magnetoresistive RAM ( MRAM ) array, marking an important development momentum for MRAM technology. AR Si
The purpose of this circuit is to generate a high voltage sine wave to drive the lamp.
After the physical object was made, there were some problems:
The current of 5V is very large, about 2A.
The ligh
