BOOTSTRAP CURRENT Meaning and
Definition
-
Bootstrap current refers to a phenomenon that occurs in electronic circuits, particularly in power amplifiers, where a small portion of the output current is used to generate a larger input current. It is a technique employed to improve the performance and efficiency of electronic devices.
In a power amplifier circuit, the bootstrap current is created by using a capacitor between the output and input terminals. When the output current increases, the voltage across the capacitor rises, causing an increase in the current flowing into the input terminal. This feedback mechanism creates a bootstrap effect, amplifying the input current.
The purpose of bootstrap current is to improve the linearity and dynamic range of power amplifiers. By increasing the input current, it helps to compensate for the non-linear behavior of electronic components, such as transistors, and results in a more accurate reproduction of the input signal.
Bootstrap current also aids in increasing the efficiency of power amplifiers. By utilizing a small fraction of the output current to generate a larger input current, it reduces the power dissipation and minimizes heat generation. This is particularly beneficial in high-power systems where heat dissipation is a critical factor.
Overall, bootstrap current is a technique that enhances the performance and efficiency of power amplifiers by utilizing a feedback mechanism to generate a larger input current. It plays a crucial role in improving linearity, dynamic range, and power efficiency in electronic circuits.

Etymology of BOOTSTRAP CURRENT
The term "bootstrap current" is derived from the concept of "pulling oneself up by one's bootstraps". This phrase, dating back to the 19th century, originally referred to an impossible or absurd action since, in reality, one cannot lift themselves off the ground by tugging at their own bootstraps.
In the field of electronics and physics, "bootstrap" refers to a feedback technique that allows a process to start or sustain itself, much like the metaphorical bootstrap concept. The "bootstrap current" specifically refers to the flow of current that is used to power some of the circuits or components necessary for a device or system to start or maintain its operation. The term was likely coined due to the analogy of the "bootstrap" concept, where an initial small current is used to generate a larger current, enabling the device to function.
