Abstract: A method for processing signals may include, in a conditionally-stable operational amplifier, shifting the gain curve of the conditionally-stable operational amplifier to a desired position, by buffering at least one output signal from at least one transconductance module within the conditionally-stable operational amplifier using a buffer. The desired position of the gain curve may be associated with a desired feedback factor. The shifting of the gain may take place without shifting a corresponding phase. The tuning of the buffer may be based on the desired position of the gain curve which is derived from feedback factor value(s) specified by an application. A phase corresponding to the desired position of the gain curve at 0 dB frequency may be greater than a threshold phase. The buffering may be tuned using at least one tunable wideband buffer so that the corresponding phase at 0 dB frequency remains higher than the threshold phase.

Abstract: A digital-to-analog converter (DAC) uses thermometer coding over a certain code range. A switch array for the certain code range is implemented into a smaller area of the integrated circuit die so as to take advantage of the lower gradient inherent in the smaller area. By implementing the certain input code range into the smaller switch array area, further improved linearity in that input code range is achieved at the expense of worse linearity in the other input code ranges, but without increasing power consumption and/or chip-area of the integrated circuit die.
