Abstract:
1. A circuit comprising: a DC-DC voltage converter having a first input to receive a DC voltage, a second input to receive a modulating control signal having at least a first state and a second state, and an output to supply a variable output voltage to a load, the DC-DC voltage converter constructed to supply the variable output voltage to the load during the first state and to stop supplying the variable output voltage to the load during the second state; an operational amplifier having a first input to receive a voltage reference, a second input to receive a feedback voltage from the load, and an output; a compensation RC network including at least one resistor and at least one capacitor; and a switch, coupled to the compensation RC network, constructed to receive the modulating control signal, connect the compensation RC network to the output of the operational amplifier during the first state, and disconnect the compensation RC network to the output of the operational amplifier during the second state.
