Usual voltages utilized in modern-day ICs may well range from approximately 1.3V to greater than 100V, reckoning on the know-how and the applying. excessive voltage is for that reason a relative suggestion.
High Voltage units and Circuits in commonplace CMOS Technologies is principally fascinated with commonplace CMOS applied sciences, the place excessive voltage (HV) is outlined as any voltage better than the nominal (low) voltage, i.e. 5V, 3.3V, or maybe reduce. during this ordinary CMOS atmosphere, IC designers are an increasing number of often faced with HV difficulties, quite on the I/O point of the circuit.
within the first staff of purposes, a wide variety of business or buyer circuits both require HV using features, or are imagined to paintings in a high-voltage setting. This contains ultrasonic drivers, flat panel monitors, robotics, car, and so forth. On the opposite hand, within the rising box of built-in microsystems, MEMS actuators more often than not utilize electrostatic forces regarding voltages within the average variety of 30 to 60V. final yet no longer least, with the appearance of deep sub-micron and/or low-power applied sciences, the working voltage has a tendency in the direction of degrees starting from 1V to 2.5V, whereas the interface has to be suitable with larger voltages, resembling 5V.
For these types of different types of purposes, it is often ideal to practice lots of the sign processing at low voltage, whereas the ensuing output rises to the next voltage point. fixing this challenge calls for a few precise activities at 3 degrees: know-how, circuit layout and format.
High Voltage units and Circuits in general CMOS Technologies addresses those issues in a transparent and arranged manner. The theoretical historical past is supported by way of sensible details and layout examples. it truly is a useful reference for researchers and execs in either the layout and machine groups.
