A Fast Transient, 24 mA Switched Capacitor Boost Regulator in 40 nm CMOS Technology
Authors: Mostafa A. Hosny, Sameh A. Ibrahim
Abstract: This work presents a fast transient boost converter in 40nm CMOS technology. The converter is fully integrated and utilizes MOS+ MOM capacitors to minimize the area. The unique pseudo-6-bit Analog to digital converter helps the system achieve its fast trainset load changes. The design also utilizes 32-phases of operation to achieve small ripples though it uses a relatively small output capacitor. The converter generates a 3 V supply from a 1.8 V input and achieves a fast transient response of 1mA to 24mA, and vice versa, in 100 ps with an undershoot and overshoot not exceeding 4% of the regulator’s output and ripples less than 40mV peak-to-peak.
