This text describes the design and theory of continuous-time sigma-delta modulators for analogue-to-digital conversion in radio receivers. The book's main focus is on dynamic range, linearity and power efficiency aspects of sigma-delta modulators, which are very important requirements for use in battery operated receivers.
