Chopping resistor
WebPull-down resistors work in the same manner as pull-up resistors, except that they pull the pin to a logical low value. They are connected between ground and the appropriate pin … Chopper stabilization, or chopping, is a technique to reduce amplifier offset voltage. However, since 1/f noise is near dc low frequency noise, it is also effectively reduced by this technique. Chopper stabilization works by alternating or chopping the input signals at the input stage and then chopping the signals … See more This article explains what 1/f noise is and how to reduce or eliminate it in precision measurement applications. 1/f noise cannot be filtered out … See more 1/f noise is low frequency noise for which the noise power is inversely proportional to the frequency. 1/f noise has been observed not only in electronics, but also in music, biology, … See more The total noise in a system is the combined 1/f noise and broadband noise from each component in the system. Passive components have 1/f noise and current noise also has a 1/f noise component. … See more After comparing the noise density graphs of a number of op amps, it becomes apparent that the 1/f corner can vary for each product. To … See more

This is done by comparing the …
Web• Ripple in the load current depends inversely on the chopping frequency, f. • To reduce the load ripple current, frequency should be as high as possible. Problem 1. A Chopper circuit is operating on TRC at a frequency of 2 kHz on a 460 V supply. If the load voltage is 350 volts, calculate the conduction period of the thyristor in each cycle. WebResistive banks are used as load banks in the testing of power generation equipment, such as industrial drives or electrical generators. They can also be as resistors for braking/chopping applications. The Resistor Bank unit dissipates the regenerative energy produced in the process of decelerating a motor.
