Electronic device and method for a limiter in an AC application

摘要

An electronic device, including a first limiter including a first transistor configured to be coupled with a first side of a channel to a first output node of a non-ideal voltage source having an inner impedance greater zero in order to limit the voltage at the first output node by drawing a current from the first output node. The second side of the channel of the first transistor is coupled to a capacitor so as to supply a current from the first output node to the capacitor, if the voltage level at the output node reaches or exceeds an upper limit.

1. An electronic device comprising:
a first limiter including a first transistor configured to be coupled with a first side of a channel to a first output node of a non-ideal voltage source having an inner impedance greater zero in order to limit the voltage at the first output node by drawing a current from the first output node, wherein the second side of the channel of the first transistor is coupled to a capacitor so as to supply a current from the first output node to the capacitor, if the voltage level at the output node reaches or exceeds an upper limit, wherein the first limiter further comprises a second transistor configured to be coupled with a first side of a channel to a second output node of a second non-ideal voltage source in order to limit the voltage at the second output node, wherein the second side of the channel of the second transistor is coupled to the capacitor so as to supply a current from the capacitor to the second output node, if the voltage level at the second output node reaches or exceeds a lower limit.
