Patent ID: 7298185

Claim:
A circuit arrangement configured to produce a reset signal after a supply voltage has fallen and risen again comprising: a first inverter having a first inverter input, a first inverter output, and a first and a second supply voltage connection, the first inverter also having a first transfer voltage; a second inverter having a second inverter input, a second inverter output, and a first and a second supply voltage connection, wherein the first inverter output is operably coupled to the second inverter input and the second inverter output is operably coupled to the first inverter input, the second inverter having a second transfer voltage, the first and the second transfer voltages having different values; an initialization circuit operably connected to the first inverter input or the second inverter input; a first rectifier element operably connected between the second inverter output and the first supply voltage connection of the first or second inverter; a first capacitance provided between the second inverter output and the second supply voltage connection of the first or second inverter; and a second capacitance provided between the first inverter output and the second supply voltage connection of the first or second inverter, wherein the first capacitance is larger than the second capacitance.
