Abstract: An automotive sensor arrangement including an automotive sensor coupled via first and second wires to signal sensor evaluation means, a signal conditioning circuit comprising a first gate means connected to provide a bias operating voltage signal on said first wire to the sensor, a second gate means of similar construction to the first gate means and mounted in the same environment and first gate means, the second gate means being coupled to the second wire of the leas means for receive the voltage signal bears a predetermined relationship to the switching point voltage of the second gate means.
Abstract: An active filter device simple in construction and low in price in which higher harmonic components can be stably suppressed without requiring a passive filter even when a load to be compensated includes a capacitative load.
