Programmable Gain

A designed method of portable virtual oscilloscope with USB interface is proposed in this paper. The programmable gain amplifier (attenuator) circuit is used to adjust the different range of inputting signal to the A/D converter's. The A/D convert is realized by using ADS830E, which is a chip with maxim 60MHz sample rate and 8-bit data width. CY7C68013A, one chip of EZ-USB FX2 series, is used to achieve the data transfer to computer in block mode. The FPGA is programmed as an external host controller to control the gain amplification and attenuation circuit, and provide the sample clock for high-speed A/D converter ADS830E, and send the data to the Slave-FIFO. Application software is designed with VC++ platform to calculate and display the received data graphically.

Wideband DC Amplifier plays an important role in scientific research and measuring instruments. This paper presents a wideband amplifier with controllable DC voltage gain with a programmable gain amplifier AD600, 12-Bit Serial D / A chip DAC7611 and FPGA-based IP MCS-51 MC as its core. Test results show that the pass band of the whole system is 0Hz ~ 10MHz, the voltage gain ranges from 0dB to 60dB, the gain step is 1dB, the maximum output voltage sine wave RMS Vo ≥ 10V, and there is no significant distortion in the output signal waveform. The system is not only characterized by its high speed, high efficiency, small size and in-built orientation of peripheral circuits, which are the features of MC constructed with a MC with FPGA, but also has advantages of flexible designing, scalability, extensibility and upgradability. Therefore it has good application prospects and research values.
