Operational amplifier

Operational amplifiers (Op Amp) have been in use for quite a long a long time now in the field of electronics and electrical engineering. A basic Op Amp has got three connections consisting of 1 output and 2 inputs. For definition purposes the two input terminals are called inverting and non-inverting inputs (Huijsing, 2011). Huijsing (2011) adds that it has been found and proven that when the voltage at both points of the inputs is the same, there will be no output on the other side. The image below

due to curtailed supply currents. The only way to make the operational amplifier survive the trend towards lower supply voltages without weakening its characteristics, is by developing very efficient operational amplifier topologies that combine low voltage and low power operation and be as simple as possible to save die area, in its contemporary sense. In this thesis, we design and analyses different design approach of operational amplifier circuits using power gating technique and MTCMOS leakage

LM2907/LM2917 Frequency to Voltage Converter June 2000 LM2907/LM2917 Frequency to Voltage Converter General Description The LM2907, LM2917 series are monolithic frequency to voltage converters with a high gain op amp/comparator designed to operate a relay, lamp, or other load when the input frequency reaches or exceeds a selected rate. The tachometer uses a charge pump technique and offers frequency doubling for low ripple, full input protection in two versions (LM2907-8, LM2917-8) and its
