摘要： Various implementations described herein refer to an integrated circuit having a first stage and a second stage. The first stage has first transistors arranged as a diode, a first latch and feedback assist to facilitate shifting an input voltage in a first voltage domain to an output voltage in a second voltage domain. The first stage uses the diode and the first latch to reduce contention between the first latch and input transistors. The diode, the first latch and the feedback assist enable activation of the input transistors with the input voltage. The second stage has second transistors arranged as a second latch followed by output buffers that provide a buffered output voltage as feedback to the feedback assist of the first stage.

摘要： In a particular implementation, an apparatus to control clamping devices includes a detection circuitry, a clamping device, inverter circuitry, and first and second control circuitry. In response to a first voltage corresponding to a gate terminal of the clamping device, the first control circuitry is configured to generate a second voltage to set the first voltage below a first voltage threshold. Also, in response to the second voltage, the second control circuitry is configured to generate a third voltage to set a voltage of the detection circuitry below a second voltage threshold.
