Furthermore, performance testing of SAR ADC is under progress. 2. Objective The Data Converters are widely used in wireless communication, digital audio and video applications. There are many kind of ADC such as flash ADC, Integrating ADC, pipeline ADC and SAR ADC. The SAR ADC can be build using resistor string DAC or Capacitor array DAC. TUTORIAL. ADC Architectures II: Successive Approximation ADCs. by Walt Kester. INTRODUCTION. The successive approximation ADC has been the mainstay of data acquisition systems for many years. Recent design improvements have extended the sampling frequency of these ADCs into the megahertz region with 18bit resolution. sar adc tutorial pdf Keywords: sar, successive to TUTORIAL 1080 Understanding SAR ADCs: Their Architecture and Comparison with Other ADCs Oct 02, 2001 Abstract: (SAR) analogtodigital converters (ADCs) represent the majority of the ADC market for medium to highresolution ADCs.

Scribd is the world's largest social reading and publishing site. sar adc tutorial pdf Low Voltage CMOS SAR ADC Page 8 Functional Decomposition This section breaks the design down into 3 separate levels. Level 0 depicts a basic block diagram showing all of the inputs and outputs of the ADC. Level 1 depicts the basic flow of the signals in the design and how the signal processing works. sar adc timing The fundamental timing diagram for a typical SAR ADC is shown in Figure 2. The end of conversion is generally indicated by an endofconvert (EOC), dataready (DRDY), or a busy signal (actually, notBUSY indicates end of conversion).
