Title: Signal processing circuit for magnetic detection type rotary angle detection sensor
Inventor: FUJIMOTO MASAHIKO
IPC: G01D5/244
Filed: 1984-05-01
Abstract: PURPOSE:To prevent erroneous operation at the time of high speed rotation and low speed rotation, by largely setting the attenuation time constant of a peak hold type signal processing circuit at the time of low speed rotation and restricting the rising in threshold voltage at the time of high speed rotation. CONSTITUTION:The analogue signal A from a magnetic detection type rotary angle (MPU) sensor is compared with threshold voltage VTH2 by a comparator 4 to output digital data D. In a peak hold (PH) circuit 5, the peak VPK of the output A is held by a capacitor C and released by a resistor R to output voltage VTH1. A variable gain amplifier 6 makes a gain variable through a variable resistor VR on the basis of the voltage signal V obtained by applying F/V conversion to the output D by a F/V converter circuit 7 to restrict the rising in threshold voltage VTH2 at the time of high speed rotation. By this method, erroneous operation due to noise at the time of low speed rotation and output loss at the time of high speed rotation are prevented.
