An automatic temperature compensated real-time clock (RTC) chip includes a clock portion having a crystal oscillator block including crystal compensation circuitry adapted to be coupled to a crystal. The crystal compensation circuitry includes a non-linear capacitor DAC including a plurality of load capacitors, wherein the load capacitors have respective switches which switch respective ones of the load capacitors to change a parallel resonance frequency (fp) generated by the oscillator block. The capacitor DAC is arranged so that Analog Trimming (ATR) bits received cause an arrangement of the switches to provide a non-linear change in overall load capacitance to result in a linear relationship between fp and the ATR bits. A temperature sensor block is coupled to the crystal for measuring a temperature of at least the crystal. An A/D converter is coupled to the temperature sensor for outputting a digital temperature signal representative of the temperature of the crystal.

A circuit and corresponding method for a precision floating gate voltage reference that uses a feedback loop, conduction of tunnel devices, and a bandgap cell to accurately program a desired charge level on a floating gate and provide a predictable and programmable temperature coefficient parameter for such voltage reference. In one embodiment, a bandgap cell is coupled through a capacitor to the floating gate storage node for providing a voltage source for canceling the temperature coefficient (TC) of the storage capacitor. The circuit and method enables TC to be minimized by either choosing the proper voltage source characteristics or alternatively, by choosing the proper ratio of two capacitors. The bandgap cell can alternatively be designed to have positive TC (PTAT voltage sources) or negative TC (VBE junction).
