Variable attenuation circuit for a differential variable reluctance sensor using current mode |
摘要 |
A variable reluctance sensor interface module having a variable attenuation circuit and a rectifier and differential to single-ended conversion circuit for operating in a current mode to attenuate a differential input voltage. The variable attenuation circuit receives an input differential voltage from a magnetic sensor and converts the differential voltage to current. First and second current sourcing circuits, each including a plurality of current sourcing branches, receive the current and provides variable current attenuation by switching in and out transistor-based current sourcing branches. The rectifier and differential to single-ended conversion circuit converts the variably attenuated currents to a voltage output.
