Abstract: A DC motor drive circuit includes a switching circuit that drives the coils of a small permanent magnetic DC motor. The drive circuit is preferably implemented in an integrated circuit device, such as a silicon CMOS device.

Abstract: An improved Hall effect sensor includes a four-terminal Hall plate with orthogonally paired terminals that produce voltage signals in response to changes in an ambient magnetic field created by the proximity of a ferrous gear tooth to the sensor. Voltage signals from orthogonally paired terminals of the Hall plate are controlled by switches that are coupled to a clock signal generator. In response to the clock signal, the switches allow current to flow in a first direction corresponding to a first phase of the clock and to flow in a second direction corresponding to a second phase of the clock. A plurality of pass gate transistors in the sensor circuitry are connected to a timing generator synchronized with the clock signal generator. The timing generator outputs are received by the gate transistors and the gate transistors control the sequence in which a plurality of capacitors are charged. This plurality of capacitors store the voltage output from the Hall plate.
