This thesis describes the design and achievement of a circuit enables to drive PZT by high voltage control. During this work we design a circuit by simulation using MULTISIM and achieve the real circuit. We choice a mixing circuit using operational amplifier, comparator and regulars components likes resistors, capacitances, diodes, thyristors and transistors..In function of the characteristic of the PZT such as a non linear device and present ferroelectric hysteresis property, PZT need more voltage to work efficiently, the design circuit must be able to boost more voltage and overcome heating however it minimize power consumption. Make a good choice of the operational amplifier and other components is the challenge; we deal on it and design a quite simple circuit. , stable, no heating, have a fast response time, a good dynamic response. Whether PZT properly work depends on the response characteristics of the PZT driver circuit, especially its dynamic response characteristic. PZT driver with dynamic response is a great need for many dynamics systems requiring precision control, precision displacement.PZT in this circuit can be used in optical communication when one part of optical fiber will be wrapping around a PZT then pass in an arm of interferometer to make measurement of phase difference. This circuit is suitable to drive such kind of PZT and eventually in auto-control system, robots, actively mode locked fiber laser.
