Abstract

Various implementations described herein are directed to an integrated circuit having first devices arranged to operate as a latch. The first devices may include inner devices and outer devices. The integrated circuit may include second devices coupled to the first devices and arranged to operate as a level shifter. The second devices may include upper devices and lower devices. The lower devices may be cross-coupled to gates of the inner devices and the upper devices. The integrated circuit may include input signals applied to gates of the outer devices and the lower devices to thereby generate output signals from the outputs of the lower devices that are applied to the gates of the inner devices and the upper devices to activate latching of the output signals.

Dependent claims

An integrated circuit, comprising:

first devices arranged to operate as a latch, wherein the first devices include inner devices and outer devices;
second devices coupled to the first devices and arranged to operate as a level shifter, wherein the second devices include upper devices and lower devices, wherein outputs of the lower devices are cross-coupled to gates of the inner devices and to gates of the upper devices;
and
input signals applied to gates of the outer devices and to gates of the lower devices to thereby generate output signals from the outputs of the lower devices, wherein the output signals are applied to the gates of the inner devices and to the gates of the upper devices to activate latching of the output signals;
wherein a first outer device of the outer devices and a first lower device of the lower devices receive a first input signal of the input signals;
wherein a second outer device of the outer devices and a second lower device of the lower devices receive a second input signal of the input signals.
