Design and Implementation of a Four Terminal Floating Amplifier and Its Application in Analog Electronics

DESIGN AND IMPLEMENTATION OF A FOUR TERMINAL FLOATING AMPLIFIER AND ITS APPLICATION IN ANALOG ELECTRONICS By José A. García Rivera The field of analog electronics has developed and matured for the past two decades. Within this field, design of analog amplifiers has received attention due to changes in technology. Amplifier circuits, considered analog devices, are found anywhere in many house electronic appliances. A variety of these devices such as the Operational Amplifier, a dominant one, Fully Differential Amplifiers, Current Feedback, and Current Conveyors are found wide spread in the integration of these electronic appliances. However, the operational amplifier is not the only device available for design and integration of complex systems. Different systems implementations call for different analog devices that suite a particular specification. This thesis presents the design and implementation of a rare, analog amplifier, active device: The Four Terminal Floating Nullor. A brief history and development of this device is presented. Circuit blocks and schematic representation from literature are shown to illustrate the different ways it has been design. Different approaches for these devices are presented with their corresponding SPICE simulations. Also, a wide variety of applications are presented where this device performs as a replacement of the Operational Amplifier.
