Abstract: Apparatuses and methods for protecting transistors through charge sharing are disclosed herein. An example apparatus includes a transistor comprising a gate node and a bulk node, a charge sharing circuit coupled between the gate and bulk nodes, and logic. The charge sharing circuit is configure to equalize charge differences between the gate and bulk nodes, and the logic is configured to enable the charge sharing circuit based at least in part on a combination of first and second signals, which indicate the presence of a condition.

Abstract: Voltage control in integrated circuits include a first voltage divider coupled to receive a reference voltage and having an output providing an adjusted reference voltage; an operational amplifier having a first input coupled to receive the output of the first voltage divider, a second input coupled to receive a feedback voltage, and an output; a voltage generation circuit responsive to the output of the operational amplifier and having an output providing an output voltage; and a second voltage divider coupled to receive the output voltage and having an output providing the feedback voltage. The first voltage divider is responsive to first control signals to adjust a voltage level of the adjusted reference voltage. The second voltage divider is responsive to second control signals to adjust a voltage level of the feedback voltage.
