Abstract: In described examples, a circuit includes a current mirror circuit. A first stage is coupled to the current mirror circuit. A second stage is coupled to the current mirror circuit and to the first stage. An output transistor is coupled to the first stage and to the current mirror circuit. A voltage divider network is coupled to the output transistor, and a power source is coupled to the second stage and to the voltage divider network.

Abstract: In an example, an apparatus includes a level-shifting circuit and a ramp detector. The level-shifting circuit has a current choke and a transistor coupled across the current choke, the level-shifting circuit adapted to be coupled to a first voltage source. The ramp detector has a ramp detector input adapted to be coupled to the first voltage source and a ramp detector output coupled to the transistor, the ramp detector adapted to be coupled to a second voltage source.

Abstract: In an example, an integrated circuit includes a junction-gate field effect transistor (JFET), a current generator, a dynamic filter, and an output transistor. The JFET has a JFET gate, a JFET source, and a JFET drain, the JFET drain adapted to be coupled to a power supply. The current generator has a current generator input and current generator outputs, the current generator input coupled to the JFET source and a first of the current generator outputs coupled to the JFET gate. The dynamic filter has a dynamic filter input and a dynamic filter output, the dynamic filter input coupled to a second of the current generator outputs. The output transistor has an output transistor gate coupled to the dynamic filter output.
