Abstract
In Chapter 3 the main low voltage system building blocks were introduced to build the Δ ∑ modulators of Chapter 2. These building blocks are integrators. In Chapter 4 the circuits to implement these with, given the low voltage restriction, and their properties are discussed. In order to be able to proceed to the design phase the required circuit specifications need to be known. It is necessary to know what gain and GBW the OTAs must be designed to have. For that reason this chapter investigates the settling process of a non-ideal Switched Opamp integrator. Finite gain and GBW effects are studied. Some other design issues are also treated.
