Objectives: A novel On Chip switched capacitor architecture to produce multiple voltages with high switching frequency and low ripple voltage. Methods: The proposed architecture uses integration of more than one converter topology to produce the scalable output voltage. The converter consists of MOSFET switches and MOS charge-transfer capacitors. The control circuitry was designed completely with digital domain to reduce static power consumed. Findings: The simulation of the scalable DC-DC converter was performed using TSMC 90nm Technology. The maximal efficiency of 80% was achieved for different topologies with 364 MHz switching frequency. Improvements: The load driving capacity of this converter was up to 5uW.
Keywords: DC-DC, DVS, High Frequency, Ripple Voltage, Voltage Converter
