摘要： The present invention relates to a band-gap reference circuit. The circuit comprises a plurality of diodes connected in series in one or more chains, a current source to flow current through the diode chains, and a selection of shunt current sources. The shunt current sources are connected in parallel with the main current sources and each, or any, can be selected in order to add current to the diode chain. In this manner, current flow through the diode chain is adjusted in order to provide a trimmable band-gap reference voltage. By adjusting the current flow, the high precision reference voltage circuit can provide a very accurate reference value for variations in process state, process error and temperature.

摘要： A microcontroller with a mixed analog/digital architecture including multiple digital programmable blocks and multiple analog programmable blocks in a communication array having a programmable interconnect structure. The single chip design is implemented by integration of programmable digital and analog circuit blocks that are able to communicate with each other. Robust analog and digital blocks that are flash memory programmable can be utilized to realize complex design applications that otherwise would require multiple chips and/or separate applications. The programmable chip architecture includes a novel array having programmable digital blocks that can communicate with programmable analog blocks using a programmable interconnect structure. The programmable analog array contains a complement of Continuous Time (CT) blocks and a complement of Switched Capacitor (SC) blocks that can communicate together. The analog blocks consist of multi-function circuits programmable for one or more different analog functions, and fixed function circuits programmable for a fixed function with variable parameters. The digital blocks include standard multi-function circuits and enhanced circuits having functions not included in the standard digital circuits. The programmable array is programmed by flash memory and programming allows dynamic reconfiguration. That is, “on-the-fly” reconfiguration of the programmable blocks is allowed. The programmable analog array with both Continuous Time analog blocks and Switched Capacitor analog blocks are offered on a single chip along with programmable digital blocks. The programmable interconnect structure provides for communication of input/output data between all analog and digital blocks.

摘要： A method of programming a programmable analog device that introduces on a single chip a set of tailored analog blocks and elements that can be configured and reconfigured in different ways to implement a variety of different analog functions. The analog blocks can be electrically coupled to each other in different combinations to perform different analog functions. Each analog block includes analog elements that have changeable characteristics that can be specified according to the function to be performed. Configuration registers define the type of function to be performed, the way in which the analog blocks are to be coupled, the inputs and outputs of the analog blocks, and the characteristics of the analog elements. The configuration registers can be dynamically programmed. Thus, the device can be used to realize a large number of different analog functions and applications.
