摘要： A relaxation oscillator includes a capacitor connected to a comparator input, current sources switched to supply power to the capacitor based on an output of the comparator, and a duplicate integrator shifting a voltage on the capacitor to offset a propagation delay through the comparator. The duplicate integrator includes current sources and a capacitor matching and switched in tandem with those within the relaxation oscillator, plus an additional current source, and is selectively switched into connection with the comparator input. By canceling the comparator propagation delay, the oscillator output frequency can be stably controlled through selection of resistive and capacitive values, using cheaper technology and tolerating large temperature, voltage and process variations.

摘要： An integrated circuit includes an output pad, an alarm output pad, and a test mode output pad. A first multi-bit register is programmable to store programmable data such as data that identifies a customer for whom the integrated circuit has been manufactured. A second multi-bit register is programmable to store customer specified threshold data. A first circuit selectively couples the first and second multi-bit registers to the output pad. The first circuit is operable responsive to the integrated circuit being placed into a test mode to perform parallel-to-serial conversion of either the customer identification data stored in the first multi-bit register or the customer specified threshold data stored in the second multi-bit register and drive the converted data for output through the output pad. The integrated circuit further includes a tamper detection circuit operable responsive to the customer specified threshold data to generate a tamper alarm signal. A second circuit selectively couples the tamper alarm signal to the alarm output pad and test mode output pad depending on whether the integrated circuit is in a test mode. More specifically, the second circuit operates to drive the alarm output pad with the tamper alarm signal when the integrated circuit is not in test mode and drive the test mode output pad with the tamper alarm signal when the integrated circuit is in test mode (with the alarm output pad driven to a known state).

摘要： A digital-to-analog converter, in response to a digital signal, selectively taps a resistor string to generate an analog output and selectively shunts around resistors in the string to voltage shift the analog output. If two supply voltage sets are present, two strings are provided. A mutually exclusively selection of outputs is made to select a source of the analog output. An integrated circuit temperature sensor uses the converter and includes a sensing circuit that determines exposure to one of a relatively low or high temperature. A measured voltage across the base-emitter of a bipolar transistor is selected in low temperature exposure and compared against a first reference for a too cold temperature condition. Alternatively, a measured delta voltage across the base-emitter is selected in high temperature exposure and compared against a second reference voltage for a too hot temperature condition. Through the comparisons, a temperature exposure detection is made.

摘要： A sensing circuit determines whether an integrated circuit is currently exposed to one of a relatively low or a relatively high temperature. A selection circuit selects a measured voltage across the base-emitter of a bipolar transistor if the sensing circuit indicates that the circuit is exposed to the relatively low temperature or, alternatively, selects a measured delta voltage across the base-emitter of the bipolar transistor if the sensing circuit indicates that the circuit is exposed to the relatively high temperature. A comparator compares the selected measured voltage against a first reference voltage indicative of a too cold temperature condition or compares the selected measured delta voltage against a second reference voltage indicative of a too hot temperature condition. As a result of the comparison, detection may be made as to whether the integrated circuit is currently exposed to a too cold or too hot temperature.
