A voltage generator is provided which is reliable, self starting and only requires a few components. The voltage generator comprises a first stage that provides a current to a second stage. The first stage has a temperature coefficient of one sign, such as positive, and the second stage has an opposing temperature coefficient, e.g. negative. The responses are summed such that the overall temperature coefficient is reduced.

Voltage generator, a method of generating a voltage and a power-up reset circuit

A low drop out voltage regulator comprising: a transistor having an input node, an output node, and a control node; a differential amplifier having an output connected to the control node of the transistor and having a first input node; and a feedback capacitor connected between the output node of the transistor and the first input of the differential amplifier, wherein a voltage at the output of the transistor is dependent on a charge across the feedback capacitor.
