摘要： A temperature compensation circuit is disclosed which has a monolithic integrated circuit with at least one integrated resistor (R84) having a first temperature coefficient, and an integrated bias circuit containing a pair of cross-coupled transistors (Q178, Q179). The temperature compensation circuit generates a compensating current (I S ) through a resistor (R S ) external to the integrated circuit, and having a second temperature coefficient different from the first temperature coefficient. The temperature compensation circuit includes a circuit (R76, 408) for passing a temperature-varying current (I t ) through the integrated resistor (R84) to generate a first temperature-varying voltage (V A ). The bias circuit (Q178, Q179) is connected to the integrated resistor (R84) and the external resistor (R S ) so that a second temperature-varying voltage (V B ) is impressed across the external resistor (R S ), which second temperature-varying voltage (V B ) is proportional to the first temperature-varying voltage (V A ) and generates the compensating current (I S ) through the external resistor (R S ).

摘要： A D/A converter converting a digital signal having n bits (n is an integer) into an analog signal includes constant-current output circuits (1₂₀ - 1₁), provided for the n bits of the digital signal, for selectively generating n constant currents on the basis of the n bits of the digital signals. The n constant currents have mutually different current values with respect to the n bits of the digital signal. The constant-current output circuits have resistance elements (14₂₀ - 14₁) respectively provided for the n bits of the digital signal. The resistance elements define the mutually different current values. The D/A converter also includes an output circuit (15) for adding the n constant currents to each other and for outputting the analog signal based on an addition result, and a temperature-dependent voltage generating part (25 - 33) for generating a temperature-dependent voltage (+V T , -V T ) which changes as a temperature around the D/A converter changes. Further, the D/A converter includes a current compensation part (34₂₀ - 34₁₃, 54₂₀) for generating a compensation voltage related to at least one of the resistance elements from the temperature-dependent voltage and for applying the compensation voltage to the one of the resistance elements. The compensation voltage compensates for a temperature-dependent variation in a characteristic of the one of the resistance elements.

摘要： A digital-to-analog converter includes a resistive divider network (10) including a plurality of series resistors of resistance R and a plurality of shunt resistors of resistance 2R' and a circuit (11) for switching a shunt resistor of the resistive divider network in the digital-to-analog converter to either of first and second reference voltages. The switching circuit includes a first switch MOSFET (441) coupling the low reference voltage to the shunt resistor, and a second switch MOSFET (42i) coupling the shunt resistor to the high reference voltage. First and second switch control circuits adjust the on resistances of the first and second switch MOSFETs to be proportional to the resistances of first and second references resistors, which have the same temperature coefficient as the resistors of which the divider network is composed. The on resistance of each of the first and second switch MOSFETs is equal to RONi, and the resistance 2R' is equal to 2R-RONi. The on resistance do not need to be binarily scaled.

摘要： A monolithic integrated circuit generates a programmable time delay under control of a digital word. The delay is generated by comparing a ramp signal to a threshold determined by the value of the digital word and appears as a time difference between a trigger pulse and a pulse generated when the value of the ramp voltage equals the value of the threshold voltage. The ramp voltage is generated by a simple resistance/capacitance charging circuit whose time constant can be adjusted by the user. The threshold voltage is set by a digital-to-analog converter (DAC) and resistor circuit which converts the digital control word into a variable voltage. In order to stabilize the device against changes in temperature and power supply variations, a voltage coupling circuit forces the threshold voltage to track changes in the ramp voltage caused by temperature and power supply variations. The coupling circuit obviates the need for precision voltage sources or current mirrors conventionally used to compensate for temperature and power supply changes. Without the need for the latter devices, the integrated circuit can be easily and inexpensively fabricated of transistors of a single bipolar type.

摘要： A low current, adaptively-biased switched resistor digital-to-analog converter (RDAC) circuit, method and apparatus are provided with a coarse trim ladder and a fine trim ladder connected with a plurality of NFET switches to generate an output reference voltage from an input supply voltage, where the bulk semiconductor substrate regions for the NFET switches in at least the fine trim ladder are driven by a unity gain buffer which is connected in feedback to receive the output reference voltage and to generate a buffered reference voltage which is directly connected to bulk semiconductor regions of the NFET switches, thereby providing a low current, low circuit area solution with reduced leakage current and temperature variation.
