• Rapidly increasing input current of microprocessors results in rising cost and motherboard real estate occupied by power delivery system. We show that a high-frequency switching DC-DC converter is feasible in 180nm-90nm technology processes for microprocessor power delivery. The current DC-DC converters on microprocessor motherboards are switching at KHz frequencies because of the strict efficiency requirements. We demonstrate a 480MHz DC-DC converter fabricated in a 90nm CMOS process. We also present measurement results on two high-speed CMOS regulation chips to prove high-frequency conversion is a fact
