摘要： The accuracy of a required tone set, digitally synthesized by a microprocessor, is improved beyond the theoretical limit of the microprocessor circuitry by producing each tone at a frequency which is a sub-multiple of the desired frequency, then multiplying to provide the desired frequency. With the addition of a multiplier such as a doubler, a better choice of oscillator frequency becomes possible which further increases the tone frequency accuracy. The microprocessor can also reduce the start up time and the time between tones, eliminating delays in transmitting a series of coded tones.

摘要： Inductors packaged with a voltage regulator for an integrated circuit within the same package are deposited to a sufficient thickness to reduce resistance and improve the quality factor. Furthermore, the voltage regulator switches currents through the inductors at a relatively high frequency such that the overall size and inductances of the inductors may be reduced. As a consequence, integrating both the integrated circuits including a voltage regulator and associated inductor array in a single package is facilitated. Other embodiments are described and claimed.

摘要： Leakage current at the inputs of an integrated circuit can be reduced by providing a master/slave arrangement wherein a plurality of slave inputs are controlled by an enable input acting as a master. When the enable input is deactivated, the slave inputs break their leakage current paths. An input structure with improved hysteresis can be provided by coupling a follow-on inverter to the output of the input stage, and coupling a hysteresis feedback circuit to the output of the follow-on inverter. The hysteresis feedback circuit is also connected to a node of the input stage other than the output thereof.

摘要： The performance of a bandgap reference circuit is improved by increasing the ΔVBE, and thereby correspondingly decreasing the input sensitivity of the error amplifier in the control loop. The ΔVBE can be increased by presenting stacked diode configurations at the amplifier inputs, by increasing the diode ratio presented at the amplifier inputs, and by providing a higher current in the CTAT leg than in the PTAT leg. The stacked diode configuration is achieved by producing isolated diodes with a triple well CMOS process. The stacked diode configuration and the triple well CMOS process also permit the input stage of the amplifier to use N-channel transistors operating in the threshold region.

摘要： Leakage currents at IC inputs can be avoided while the IC is disabled by providing a switch that is responsive to deactivation of an enable input to isolate functional circuitry of the IC from one of the power supply nodes of the IC. This eliminates power supply current while the IC is disabled. Further unwanted current flow can be avoided while the IC is disabled by providing a switch that is responsive to the enable input for selectively connecting and disconnecting the base of a reference voltage transistor to and from the transistor's grounded collector, which collector is defined by the substrate of the IC. Disconnection of the base from the grounded substrate/collector eliminates base current and thus prevents emitter-to-collector current flow through the transistor when the IC is disabled.

摘要： A sub-bandgap reference circuit yielding a reference voltage smaller than the bandgap voltage of silicon. The circuit generates a negative temperature coefficient signal Vbe and an oppositely tracking (positive temperature coefficient) &Dgr;Vbe, and takes the average of two signals related to &Dgr;Vbe-Vbe to yield a temperature-compensated voltage of one-half the bandgap voltage of silicon. The circuit features an unequal area current mirror feeding the diodes and resistors used to generate the &Dgr;Vbe-Vbe signals using low supply voltages (less than 1.5 volts). A standard CMOS implementation provides low power consumption at a supply voltage of only 1 volt with a good temperature coefficient. The averaging circuit may be implemented by a continuous time divider or by using switched capacitor techniques. The loop amplifier used in the &Dgr;Vbe-Vbe circuitry operates with low headroom in part due to a n-well biasing scheme that lowers the effective threshold voltage of the p-channel FETs used in the loop amplifier.
