Abstract:
1. A circuit portion, comprising: a latch, having a first terminal and having a second terminal; a first N-channel transistor, having a first current electrode, a second current electrode coupled to a power supply voltage, and a control electrode coupled to a first conductor of a first differential pair; a second N-channel transistor, having a first current electrode coupled to the first current electrode of the first N-channel transistor and coupled to the first terminal of the latch, a second current electrode coupled to the power supply voltage, and a control electrode coupled to a first conductor of a second differential pair; a third N-channel transistor, having a first current electrode, a second current electrode coupled to the power supply voltage, and a control electrode coupled to a second conductor of the first differential pair; and a fourth N-channel transistor, having a first current electrode coupled to the first current electrode of the third N-channel transistor and coupled to the second terminal of the latch, a second current electrode coupled to the power supply voltage, and a control electrode coupled to a second conductor of the second differential pair.
