The purpose of this study is to present and characterize an 8 bit AD converter implemented with flash architecture. Flash architecture provides with one of the fastest and easiest ways to convert analog input signals to digital outputs. Analog-to-digital conversion is the process in which a continuously varying analog signal is transformed into a multilevel digital signal. Analogue electrical waveforms are applied to the converter and are sampled at a fixed rate. Sample values are then expressed as a binary number consisting of 0’s and l’s. The resulting digital code can be used to encode digital audio, applications in video and image processing systems. The more bits that are used to represent the amplitude of the original signal, the higher the quality of the output. 8 bit sampling is typically used to encode speech, 16 bit to encode music.
