<p>The first part of this thesis contains a literature study of current tuning techniques for continuous-time integrated filters. These tuning methods are characterised by which quantity they measure, their dependence on certain characteristics of the input signal, or matching of components on chip. The structure of the different tuning schemes are explained. The merits and drawbacks as well as achieved accuracies of previous works are summarised. </p><p>The second part is a study of wave active filters (WAFs), a less common structure for implementing active filters. In this structure the filter is realised by simulating the forward and reflected voltage waves present in the prototype filter. The main advantage of this is that the inherent low sensitivity of doubly terminated ladder-filters is better preserved than in many other structures. Two Mosfet-C realisations of Wave Active Filters have been suggested and high-level simulations have been used to compare them to the originally proposed implementation as well as a leapfrog implementation.</p>
