| Abstract: | A kind of controllable broadband direct current amplifier is designed to use the MCU 80C51 and FPGA as the core of the system,and with the variable-gain amplifier AD603 and the Programmable-Gain Amplifier THS7001 at the same time.The bandwidth could be chosen as either（0～5）MHz or（0～10）MHz,and the gain could be adjusted between（0～60）dB.The system could drive the load impedance as low as 50 Ω,and the output voltage could be 22 V.The system has the simple structure and the friendly interface. |
