Abstract: An example current mirror arrangement includes a current mirror circuit having an input transistor and an output transistor, where the base/gate terminal of the input transistor is coupled to its collector/drain terminal via a transistor matrix that includes a plurality of transistors. Transistors of the transistor matrix, together with the input transistor, form two parallel feedback loops, such that the input transistor is part of both loops. The first loop is a fast, low-gain loop, while the second loop is a slow, high-gain loop. At lower input frequencies, the high-gain loop may properly bias and accurately generate voltage at the base/gate terminal of the input transistor, while at higher input frequencies the fast loop may significantly extend the linear operating frequency band. Consequently, a current mirror arrangement with improvements in terms of linearity and signal bandwidth may be realized.

Abstract: A DLDO has a configuration that mitigates performance degradation associated with limit cycle oscillation (LCO). The DLDO comprises a clocked comparator, an array of power transistors, a digital controller and a clock pulsewidth reduction circuit. The digital controller comprises control logic configured to generate control signals that cause the power transistors to be turned ON or OFF in accordance with a preselected activation/deactivation control scheme. The clock pulsewidth reduction circuit receives an input clock signal having a first pulsewidth and generates the DLDO clock signal having the preselected pulsewidth that is narrower that the first pulsewidth, which is then delivered to the clock terminals of the clocked comparator and the digital controller. The narrower pulsewidth of the DLDO clock reduces the LCO mode to mitigate performance degradation caused by LCO.
