Patent ID: 7166991

Claim:
A circuit for a current mode voltage regulator having dynamic biasing for the complete loop transfer function is comprising: an operational transconductance amplifier (OTA), wherein its effective transconductance gm is linearly dependent upon its biasing current, having inputs and an output, wherein its output is connected to a means of constant current amplification and the inputs are a reference voltage and a feedback voltage from a voltage divider, wherein said biasing current, which is generated by amplification of the output current of said OTA using a constant current amplification factor is forming a feed forward loop; said means of constant current amplification having an input and two outputs, wherein its input is said output current of said OTA and a first output is said biasing current of said OTA and a second output is the output current of said voltage regulator; a low-pass filter stabilizing said biasing current; and said voltage divider providing a voltage being linearly correlated to the output voltage of said voltage regulator and wherein said voltage provided by the voltage divider is used as an input of said OTA forming a negative feedback loop by connecting the regulator output to the OTA input.
