摘要
介绍了芯片ADC0809的工作原理和如何利用Verilog HDL硬件描述语言设计ADC0809采样控制电路,同时给出采样控制电路在QuartusⅡ4.0软件环境下的功能仿真波形,并通过Altera公司的CPLD器件EP1K30TC144-3和GW48 EDA教学试验系统来实现A/D采样控制器。实践证明设计的电路能够稳定、可靠的工作。
In this paper, the principle of ADC0809 is introduced at tirst, then how to design ADC0809 sampling controller based on Verilog HDL is stated, and the circuit＇s function simulation waveform on Quartus Ⅱ 4.0 is given, and at last the circuit is implemented by configuring the Altera CPLD device EP1K30TC144- 3 and the GW48 EDA system for teaching and experiments. ADC0809 sampling controller is proved to be stable and reliable.
