In circuitry to capture differences between magnitudes of first and second comparator input signals in capture operations defined by a clock signal, first and second nodes are connectable to a tail node receiving a cock-signal-independent bias current along first and second paths. During each capture operation, switching circuitry controls connections between the tall node and the first and second nodes based on the input signals to divide the bias current between the first and second paths depending on the input signal magnitude difference. The switching circuitry comprises first and second transistors arranged such that conductivity of connections between the tail node and the first and second nodes Is controlled by the magnitudes of the input signals, and third and fourth non-clocked transistors controlled by a clock-signal independent gate bias signal.

Comparator circuitry

A voltage regulator for one or more dies in a multi-stack integrated circuit includes an inductor located on a die, a voltage controller that is electrically coupled to the inductor and is also located on the die, and a capacitor that is electrically coupled to the inductor and the voltage controller and is also located on the die. The inductor defines an interior space and the voltage controller and the capacitor are located within the interior space of the inductor. The inductor can be a lateral inductor or a through layer via inductor. The multi-stack integrated circuit may have multiple dies. A voltage controller may be electrically coupled to each of the dies, although it may be located on only one of the dies. Alternatively, separate voltage controllers may be electrically coupled to each of the multiple dies and may be located on each of the respective dies.
