Abstract: An integrated circuit amplifier configurable to be either a programmable gain amplifier or an operational amplifier comprises two output blocks, one output block is optimized for programmable gain amplifier operation, and the other output block is optimized for operational amplifier applications. A common single input stage, input offset calibration and bias generation circuits are used with either amplifier configuration. Thus duplication of the input stage, offset calibration and bias generation circuits are eliminated while still selectably providing for either a programmable gain amplifier or operational amplifier configuration.

Abstract: A micro-coded sequencer controls complex conversion sequences independent of a central processing unit (CPU). Micro-coding provides for easily adding new process steps and/or updating existing process steps. Such a programmable sequencer in combination with an analog-to-digital conversion module such as an analog-to-digital converter (ADC) or a charge time measurement unit (CTMU), and digital processing circuits may be configured to work independently of the CPU in combination with the micro-coded sequencer. Thereby providing self-sufficient operation in low power modes when the CPU and other high power modules are in a low power sleep mode. Such a peripheral can execute data collection and processing thereof, then wake the CPU only when needed, thereby saving power. Furthermore, this peripheral does not require CPU processing so that time critical applications that do require control by the CPU can operate more efficiently and with less operating overhead burden.

Abstract: Temperature is determined by measuring the time it takes to charge a capacitor with a resistive temperature sensor. A clock, time counter, a voltage comparator and voltage reference are used in determining a course time measurement. The time measurement resolution is enhanced with the addition of a constant current source charging another timing capacitor within a single clock pulse time to provide a fine time measurement.
