摘要： An integrated circuit. The integrated circuit comprises a timebase generator and a switch mode direct current-to-direct current (DC-to-DC) voltage converter coupled to the timebase generator. The timebase generator comprises a first linear feedback shift register (LFSR), a signal generator having an input coupled to an output of the first LFSR; and a digital divider comprising a second LFSR and a programmable digital divider, wherein a clock input of the programmable digital divider is coupled to an output of the signal generator, wherein an output of the programmable digital divider is coupled to a clock input of the first LFSR and is coupled to a clock input of the second LFSR, and wherein an output of the second LFSR is coupled to a program input of the programmable digital divider.

摘要： An integrated circuit. The integrated circuit comprises a timebase generator and a switch mode direct current-to-direct current (DC-to-DC) converter coupled to the timebase generator. The timebase generator comprises a linear feedback shift register (LFSR) having an output and a logic circuit comprising a first logic inverter, a first AND logic gate, and a first multiplexer, wherein the first logic inverter has an input coupled to a most significant bit of the output of the LFSR, wherein the first AND logic gate has a first input coupled to a second most significant bit of the output of the LFSR and a second input coupled to an output of the first logic inverter, wherein a selector input of the first multiplexer is coupled to an output of the first AND logic gate.
