Abstract
The present Diploma Thesis treats the design of an analog Signal Conditioning circuit in CMOS integrated circuit technology connected in negative feedback to an HMC 1001/2 anisotropic magnetoresistance sensor from Honeywell. Initially, the AMR phenomenon as well as characteristics of the AMR sensor relevant to the following design are discussed. Next, specifications of the circuit to be designed are set based on the desired performance of the final system. That is followed by the design of the Signal Conditioning Circuit in CMOS integrated circuit technology. Finally, the whole system is simulated and its performance evaluated.
