Abstract:
1. A system that boosts voltage upon a node connected to pixels in a complementary metal-oxide-semiconductor (CMOS) imaging system-on-chip (iSoC) sensor, comprising: a vertical output driver that outputs a signal upon a node connected to at least one of gates of reset transistors of pixels in a pixel array or gates of transfer transistors of pixels in the pixel array; a pre-charger that transitions a voltage of the node to a first voltage level, the pre-charger comprises a high pre-charge circuit and a low pre-charge circuit, the high pre-charge circuit comprises two p-type metal-oxide-semiconductor (PMOS) transistors with isolated n-wells, and the low pre-charge circuit comprises two n-type metal-oxide-semiconductor (NMOS) transistors with isolated p-wells; and a booster with operation that varies according to at least one degree of freedom, the booster further adjusts the voltage of the node from the first voltage level to a second voltage level.
