Mixed Signal Techniques

  • Olli Vainio


Mixed signal circuits include both analog and digital functions. Mixed signal techniques that are commonly encountered in signal processing systems are discussed in this chapter. First, the principles and general properties of sampling and analog to digital conversion are presented. The structure and operating principle of several widely used analog to digital converter architectures are then described, including both converters operating at the Nyquist rate and oversampled converters based on sigma-delta modulators. Next, different types of digital to analog converters are discussed. The basic features and building blocks of switched-capacitor circuits are then shown. Finally, mixed-signal techniques for frequency synthesis and clock synchronization are explained.
