Discrete sizing of analog integrated circuits

The sizing of the analog blocks of integrated circuits must be computed predominantly automatically to ensure the efficiency of the design flow for integrated circuits also in future. The values should be assigned to the circuit parameters in the sizing step such that the amount of manufactured circuits which fulfil the specifications for various operation conditions is high. Current tools can not solve this task in many cases if discrete design parameters have to be considered at the same time. However, discrete parameters are crucial for the sizing in future technologies and for the consideration of layout specific problems. This thesis presents two new approaches which use SQP and Branch-and-Bound to solve the described problem. The approaches are evaluated by solving the sizing task for several test circuits.
