Abstract :
The sigma-delta technique for data conversion has become a standard in audio hi-fi and communication systems for medium and high performance applications. This paper presents an approach for the design of band-pass sigma-delta modulators to be used in digital radio systems. A new circuit solution with numerical simulations is presented
