Open loop vs closed loop hall effect

The negative feedback employed in closed-loop architecture allows us to reduce the non-ideal effects such as linearity and gain errors. That’s why, unlike an open-loop configuration, a closed-loop architecture is not affected by drift in the sensor sensitivity. Hence, a closed-loop configuration offers a higher … Ver mais The structure of a Hall effect-based open-loop current sensor is shown in Figure 1. The current to be measured flows through a conductor that is inside a magnetic core. In this way, the … Ver mais Assume that there is no magnetic core. The magnetic field at a distance of r from an infinitely long, straight conductor that carries an electric … Ver mais With an open-loop configuration, non-ideal effects, such as linearity and gain errors, can affect the measurement accuracy. For example, if the … Ver mais As shown in Figure 1, the magnetic core is designed with an air gap in which the Hall sensor is placed. The air gap can lead to fringing flux phenomenon where some flux lines deviate from their straight path and hence, do not go … Ver mais Web12 de jan. de 2024 · Having said that, increasing the loop gain by increasing the dc open loop gain increases the open loop gain at all frequencies in which case zeta is reduced as are stability margins. Just as an aside. In a practical op amp it is very difficult to move the poles independently like this.
