    摘要: An integrated circuit provides a power on reset signal with respect to a supply voltage level supplying the electronic device. The integrated circuit comprises a bias current generating stage having a first current mirror and an output stage having first, second and third series connected MOS transistors. A connection between the second MOS transistor and the third MOS transistor forms a POR output node. A gate of the second MOS transistor and a gate of the third MOS transistor are coupled to each other and to the first current mirror. This allows a current through the third MOS transistor when the supply voltage is higher than a first MOS transistor threshold and a current through the second MOS transistor only when the supply voltage is greater than or equal to the sum of the first MOS transistor threshold and a second MOS transistor threshold voltage.

    摘要: An electronic device has an LDO regulator for varying loads. The LDO regulator includes a primary supply node coupled to a primary voltage supply. An output node provides a secondary supply voltage and a load current. A bias current source generates a bias current. A gain stage coupled to the bias current source increases the maximum available load current. The gain stage includes a first MOS transistor biased in weak inversion coupled to a current mirror which mirrors the drain current through the first MOS transistor to the output node. The gate-source voltage of the first MOS transistor increases in response to a decreasing secondary supply voltage level at the output node to increase the available load current.
