In this work performance limitations of various pulse-width modulation
architectures are compared. First, classical pulse-width modulation based
analog digital converter is analyzed. Then, pulse-count modulation based
digital-analog converter is explored. The structures are implemented on AlteraTM
Stratix III FPGA. A sawtooth test signal is generated to analyze the
performance of the DAC structures. Maximum effective resolution is calculated
depending on the architecture selected. The paper is especially useful for the
practicing engineers who deal with embedded system design and develop
pulse-width modulation and pulse count modulation based digital-analog
converters on microcontrollers and FPGA systems.
