    Abstract: An SRAM having two capacitors connected in series between respective bit storage nodes of each memory cell. The two inverters of the memory cell are powered by a positive voltage and a low voltage. The two capacitors are connected to each other at a common node. A leakage current generator is coupled to the common node. The leakage current generator supplies to the common node a leakage current to maintain a voltage which is approximately halfway between the voltages of the high and low SRAM supplies.

    Abstract: Various embodiments provide an optical image stabilization circuit that synchronizes its gyroscope and drive circuit using gyroscope data ready signals and gyroscope reset signals. In response to a gyroscope data ready signal, the optical image stabilization circuit synchronously obtains position measurements of a camera lens when power drive signals are not transitioning from one power level to another power level, and synchronously transitions the power drive signals simultaneously with gyroscope reset signals. By synchronizing the gyroscope and the drive circuit, the gyroscope and other onboard sensing circuits are isolated from noise generated by the drive circuit.

    Abstract: Gain offset and voltage offset compensation for a controllable gain element of a circuit is effected in response to a gain offset value and voltage offset value. A current operating condition of the circuit is sensed and compared to a nominal operating condition. If the current operating condition is outside the nominal operating condition by more than a threshold, a calibration operation to set the gain and voltage offset values is performed. The gain offset value is selected as a function of the sensed current operating condition. With respect to the voltage offset, differential input terminals of the controllable gain element are shunted and the output is measured. The measured output value of the controllable gain element is applied as the voltage offset value. The operating conditions at issue may be one or more of supply voltage and temperature.
