摘要： A differential oscillator is supplied with a constant total current. A signal-controlled single-ended shunt circuit bypasses current around the oscillator thus varying the tail current oppositely. This in turn varies the signal delay in the oscillator transistors and hence oscillator frequency.

摘要： A circuit for supplying a pair of currents that vary in opposite directions as a function of a control current. The pair of currents are coupled to an amplifying stage in which the gain varies in accordance with the relative magnitude of the currents. The circuit includes a differential current source having two output current terminals and a pair of controlled inputs. Both inputs are coupled to individual current sources. One input includes a resistor-diode current sink and the other input includes a current mirror sink. The control current is coupled to the current mirror thus varying the load on the related differential inputs. The current mirror input is also coupled to the diode current sink in the one differential input so that a delay can be introduced into the response to control current. That is, the control current must exceed a predetermined value before the gain reduction action occurs.

摘要： A plurality of oscillator-modulator combinations is incorporated into a monolithic integrated circuit. A single pole multiple position switch is used to energize a single oscillator at a time, and a filter having a plurality of inputs and a common output is coupled to the modulator outputs. The modulators each have a common modulation input. Using this combination, a very simple switch can be used to control the modulated signal output at different carrier frequencies.

摘要： A switching mode voltage regulator circuit that operates at reduced quiescent current levels is provided. The voltage regulator preferably includes a control circuit and a switching element that connects and disconnects filter circuitry from the control circuit. An error amplifier in the control circuit is placed in a micropower operating state when the regulator is in standby mode to reduce quiescent current.

摘要： A circuit and method for controlling a switching voltage regulator having (1) a switch including one or more switching transistors and (2) an output adapted to supply current at a regulated voltage to a load including an output capacitor. The circuit and method generates a control signal to turn said one or more switching transistors OFF under operating conditions when the voltage at the output is capable of being maintained substantially at the regulated voltage by the charge on the output capacitor. Such a circuit and method increases the efficiency of the regulator circuit particularly at low average current levels.

摘要： An enable circuit that integrates thermal shutdown capability. The enable circuit utilizes a temperature insensitive threshold detector network that provides a desired biasing current when the ON/OFF signal applied at its input exceeds a preselected voltage. Thermally sensitive circuitry connected between the input of the threshold detector network and ground remains off when the ON/OFF signal is equal to the preselected voltage and the temperature of the enable circuit is below a preselected maximum temperature. However, when the temperature of the enable circuit reaches the preselected maximum temperature, the thermally sensitive circuitry turns on, clamping the input signal to the threshold detector network below the preselected voltage.

摘要： A maximum swing bipolar charge pump retains a cascode switching configuration for high breakdown. The charge pump includes a charge pump capacitor with a first plate connected to supply in the conventional manner. A first cascode-connected NPN transistor is utilized to switch the second plate of the pump capacitor to the supply. A second cascode-connected NPN transistor is utilized to switch the second plate of the pump capacitor close to ground. An additional bipolar biasing network holds the second NPN transistor out of heavy saturation when the second plate of the pump capacitor is switched close to ground, thereby preserving fast turn-off time and maximum voltage swing with the constraint of a bipolar cascode configuration.

摘要： An adaptive gate charge circuit for switching a power FET on in response to a control signal. The adaptive gate charge circuit includes driving circuitry that responds to assertion of a control signal by providing a charging current from a charge pump reservoir capacitor to the gate of the power FET for an initial time period sufficient to switch the power FET on. After the initial time period, holding circuitry provides holding current from the charge pump to the power FET gate to compensate for charge leakage. Current limiting circuitry connected to the holding circuitry limits current drain from the charge pump after the initial time period to the holding current required to compensate for charge leakage plus a minimum additional current.

摘要： A wide bandwidth amplifier is coupled to the differential output of a four-quadrant multiplier. The amplifier includes a differential to single-ended input stage driving the inverting input of an operational amplifier which has its noninverting input operating at a reference potential level. The amplifier output is coupled by way of a level shifting means to the circuit output terminal which is thereby referenced to ground potential. The circuit output terminal is returned through a resistor to a source of opposite polarity power supply so that the output terminal can swing above and below ground. The second supply is only connected by way of the output terminal so that it does not require an extra package pin.
