Fast and flexible CCD-driver system using fast DAC and FPGA

Abstract: We have developed a completely new type of general-purpose CCD data acquisition system which enables one to drive any type of CCD using any type of clocking mode. A CCD driver system widely used before consisted of an analog multiplexer (MPX), a digital-to-analog converter (DAC), and an operational amplifier. A DAC is used to determine high and low voltage levels and the MPX selects each voltage level using a TTL clock. In this kind of driver board, it is difficult to reduce the noise caused by a short of high… Show more

“…The CCDs were operated in a vacuum chamber in order to keep water off them. We employed a MiKE system, 16 which was a CCD operation system developed in Osaka University, to generate bias and clock voltages to operate CCDs. The MiKE system flexibly changes the timing and the amplitude of the clock voltages, such as horizontal clock and vertical clock, thanks to a combination of Field Programmable Gate Array(FPGA) and Digital-Analog Converter(DAC).…”

“…At this time, we applied a transfer pulse to the CCD to drive the charge packets under the pixel simultaneously. The charge packets in the potential well moved one electrode to the right at the same time; as such, the charge packets follow the moving image, as shown in Figure 5b and, thus, continue to move repeatedly until the end of the exposure [31]. …”
