amplifier (op-amp) is an integrated circuit that amplifiers the difference between two inputs voltages and produces a single output. The op-amp is prevalent in analogue electronics‚ and can be thought of another electronics device which is bipolar or field-effect transistor. The op-amp is one of the basic building blocks of linear design. Its consists of two high impedance inputs‚ one called the Inverting input ( - ) which inverts the phase of the signal‚ the other called the Non-inverting input ( + ) which

CHAPTER TWO 2.0. LITERATURE REVIEW In a commercial transaction system‚ a system user uses a card device to interact with sales or transaction terminals to conduct cashless transactions. Each terminal processes data including a balance stored on the card device and updates the stored data at the end of the transaction. The system is specially designed for purchases of items or transactions of relatively small monetary value‚ where purchases are generated unattended by salespersons. In this manner

derives from its location. Stephen Cohn describes this importance “While history has been unkind to Pakistan‚ its geography has been its greatest benefit. It has resource rich area in the north-west‚ people rich in the north-east.” Pakistan is a junction of South Asia‚ West Asia and Central Asia‚ a way from resource efficient countries to resource deficient countries. The world is facing energy crisis and terrorism. Pakistan is a route for transportation‚ and a front line state against terrorism

Figure 1. Mask set design. Shown is a single “mask unit cell” and its contents. Each completed 2 inch wafer contains roughly forty whole mask cells. ECE 4752 Wafer Test Procedures In order to evaluate the electrical characteristics of the CMOS devices fabricated in ECE/ChBE 4752‚ a probe station is used to connect test equipment to the devices on-wafer. This is accomplished by positioning probes with mechanical manipulators such that their tips rest on metal pads on the wafer. Care must be
