Most operational amplifiers require dual power supplies (positive and negative power supplies), and only a few operational amplifiers can work under single power supply conditions, such as LM358 (dual
This paper proposes a new design of Ethernet telephone, which uses SDA80D51 chip as the main control unit and RTL8019AS as the network interface module, realizing a highly integrated and cost-effectiv
