What is a high side driver?
A high side driver is one in which the switching element is between Vcc and the load.
A low side driver is one in which the switching element is between the load and common.
A self-contained load such as a DC motor, solenoid/relay, light or LED string, can usually be driven by either method..
Where did the term bootstrapping come from?
The term “bootstrapping” originated with a phrase in use in the 18th and 19th century: “to pull oneself up by one’s bootstraps.” Back then, it referred to an impossible task. Today it refers more to the challenge of making something out of nothing.
What are bootstrapping strategies?
Bootstrapping is a technique used by individuals in business to overcome obstacles, achieve goals and make improvements through organic, self-sustainable means with no assistance from outside.

What is bootstrap power supply?
Simple in structure, a bootstrap circuit is a step-up charge pump composed of a switch, a capacitor, and a diode, where a voltage equal to the switch voltage (Vin) plus the internal supply voltage is used as the gate drive for the high-side Nch MOSFET. …
What is meant by bootstrapping?
Bootstrapping is building a company from the ground up with nothing but personal savings, and with luck, the cash coming in from the first sales. The term is also used as a noun: A bootstrap is a business an entrepreneur with little or no outside cash or other support launches.
What is a cascode amplifier?
The cascode is a two-stage amplifier that consists of a common-emitter stage feeding into a common-base stage. … In modern circuits, the cascode is often constructed from two transistors (BJTs or FETs), with one operating as a common emitter or common source and the other as a common base or common gate.
What is sweep signal?
A glide sweep (or chirp) is a continuous signal in which the frequency increases or decreases logarithmically with time. This provides the complete range of testing frequencies between the start and stop frequency.
What is voltage sweep?
[′swēp ‚vōl·tij] (electronics) Periodically varying voltage applied to the deflection plates of a cathode-ray tube to give a beam displacement that is a function of time, frequency, or other data base.
What is bootstrap sweep circuit?
A bootstrap sweep generator is a time base generator circuit whose output is fed back to the input through the feedback. This will increase or decrease the input impedance of the circuit. This process of bootstrapping is used to achieve constant charging current.
Why do we use cascode amplifier?
It has advantages for increasing bandwidth and for high-voltage amplifier applications. A cascode amplifier consists of a common emitter stage loaded by the emitter of a common base stage. A cascode amplifier has a high gain, moderately high input impedance, a high output impedance, and a high bandwidth.
What is high side mosfet?
“High-side” means the current travels from the supply through the mosfet to the load and then to ground. Another way to put that is: Low-side = mosfet source to ground, drain to load, load to supply. High-side = mosfet drain to supply, source to load, load to ground.
What is high side driver and low side driver?
High-Side vs. A low-side driver is placed between the load and ground, whereas a high-side driver, shown in 2(b), is placed between the load and the supply voltage. The low-side driver is often used for powertrain-related loads such as motors, solenoids, and heaters.
What is the high side?
The high side, or discharge line, will be the line connected to the compressor from the bottom or lower position. … This is where freon exits the compressor as a liquid.
What is a bootstrap circuit used for?
A bootstrap circuit is used in half-bridge configurations to supply bias to the high-side FET.
What is an channel Mosfet?
The N-Channel MOSFET has an N- channel region located in between the source and drain terminals. It is a four-terminal device having the terminals as gate, drain, source, body. In this type of Field Effect Transistor, the drain and source are heavily doped n+ region and the substrate or body are of P-type.
Can you pull yourself up by your bootstraps?
As self-levitating by pulling on one’s bootstraps is physically impossible, this is often used by the bootstrappers themselves to deny the possibility that the bootstrap campaign is indeed concocted and artificial.
What is Miller sweep circuit?
Miller sweep circuits are the most commonly used integrator circuit in many devices. It is a widely used saw tooth generator.
What are the advantages and disadvantages of single stage amplifier?
Advantages, disadvantages and applications of single stage RC coupled CE amplifierIt has wide frequency response and large bandwidth.It is most convenient and least expensive amplifier.It provides high audio fidelity.It has low amplitude distortion.It provides low frequency distortion.
