摘要： A silicon integrated oscillator circuit is connected with a capacitor and produces a highly precise and stable triangular output voltage. Both the charge current and the discharge current are proportional to one reference current. A switching circuit terminates the charge and discharge intervals when the capacitor voltage reaches a level that is equal to intermediate points on first and second resistive-voltage-divider circuits, respectively. This is accomplished by a differential-transistor-pair comparator having the base of one transistor connected to a high voltage one of the reference points and a third transistor, which is connected collector to emitter across the one transistor, having a base connected to a low voltage one of the reference points.

摘要： A cross-coupled latch circuit in which first and second switching transistors are each connected as a current mirror with a diode. The base of each switching transistor is cross-coupled to the collector of the other switching transistor by a resistor and a diode. The collector of each switching transistor is connected to the voltage source terminal by a resistor. The switching transistors are prevented from saturating in their low states so as to increase switching speed.

摘要： A sawtooth-voltage-generating oscillator has a high gain comparator circuit formed of two differentially-connected NPN transistors driven respectively by two PNP transistors that leads to a very linear ramping of the sawtooth waveform, and at the same time, provides a sawtooth voltage swing at low supply voltages that may be within no more than 1.5 volts less than that low supply voltage. This oscillator also has the capability of working in the feed forward mode in a switching mode power supply while maintaining a stable oscillation frequency over a wide range of supply voltages.

摘要： In a silicon integrated circuit there is formed a silicon photo-diode connected to the input of a multiple stage current-mirror amplifier. The output branch of the amplifier is connected between the two power supply terminals. When voltage is applied to the two power supply terminals the current that flows is the sum of the currents in each branch of the three stage amplifier. Since each branch current is proportional to the current "generated" by the photo-diode, the total power supply current is proportional to the ambient light intensity. Thus a small two terminal photo-conductor type sensor is made that exhibits an unusually high sensitivity that is stable with temperature.

摘要： An integrated circuit photo sensor has a principal photo diode whose reverse voltage is maintained at a low and relatively invariant value by a circuit comprised of a biasing diode string in series with a small auxiliary photo diode and an emitter follower coupling the diode string bias voltage to the principal photo diode. This results in reliable starting without contributing a DC component of current in the power supply so this circuit is suitable for use in a linear two-terminal-type integrated-circuit photo sensor.

摘要： A pulsing oscillator employs a capacitor that is charged through a diode from a current-source circuit and repeatedly discharges through a PNP and an NPN transistor when the capacitor voltage reaches a predetermined voltage. Another transistor is connected in shunt with a diode and capacitor, and is turned on only when the first mentioned transistors turn on so as to divert the frequency controlling current from the current source away from the capacitor during the time of discharge. The output pulse width remains constant for all values of control current and large control currents may be used without risking the "latching-on" by large control currents of the transistors intended to carry the discharge current from the capacitor.

摘要： A motor control circuit wherein Bemf zero crossings are sensed to provide phasing information. To avoid incorrect timing (due to detection of zero crossings which may be caused by switching noise when the power transistors switch to commutate other phases), the Bemf detection is masked. Advantageously, the Bemf detection is masked not only for the normal masking period (including an additional percentage beyond the minimum period), but is also for an additional period, if the Bemf output is not of the expected polarity.

摘要： An amplifier in which a clamping circuit is an integral part of the output stage structure is used as a voice coil driver for positioning the heads of a memory disk drive. The output stage, operating in class AB, comprises two bipolar transistors, the source and the sink transistors, serially connected between a power supply and a ground terminal, the serial connection between the emitter of the first transistor and the collector of the second transistor being the output terminal of the output stage. The base terminals of the two output transistors are connected to a bias circuit and to an input transistor, used as the signal control element. The clamping circuit is directly connected with the base terminals of the output transistors to limit the voltage on said base terminals between a first and a second voltage reference.
