A method reading bank register values is provided. Register values are stored in a readback bank. The register values are output sequentially from the serial bank. An indicator is received by the serial bank. A determination is then made as to whether the indicator was received by the serial bank prior to completion of the outputting of the register values. If the indicator was received prior to completion of the outputting of the register values, the register values are loaded into the serial bank from the readback bank.

A non-linear correction current ICTAT (current complementary to the square of absolute temperature) is generated from a current IPTAT (current proportional to absolute temperature) and a current ICTAT (current complementary to absolute temperature), both modified in a circuit having a topology and components which capitalize on the logarithmic relationship between transistor collector current and base-emitter voltage. The resulting ICTAT current (current complementary to the square of absolute temperature) is injected into a node of a bandgap reference circuit to compensate for non-linear temperature effects on output voltage. A more general correction circuit generates both IPTAT and ICTAT, and applies each to a respective multiplier which, in a preferred embodiment, is a current DAC configured as a multiplier. Control inputs CTL and CTL to respective multipliers set the amplitudes of the modified IPTAT and ICTAT output currents, which are then summed to generate the compensating current Icomp which is injected to the appropriate node in the bandgap reference circuit as described above. By adjusting the relative amplitudes of the IPTAT and ICTAT currents, a wide range of compensating current versus voltage curves is produced, allowing the optimization of a wide range of bandgap reference circuits.

Systems and methods are provided for providing a filtered, thermometer coded output signal from an N bit digital input, where N is an integer greater than one. A truncated lookup table provides a corresponding truncated thermometer code in response an address related to the N bit digital input. A code recovery assembly transforms the truncated thermometer code into a thermometer coded output according to a recovery bit associated with the N bit digital input.
