This work presents a start-up boosting circuit designed for fast stabilization of a 2-transistor voltage reference. A clock injection method is used to induce a large bias on the 2-transistor voltage reference resulting in a fast output voltage settling which is critical to reducing initialization time for analog components, reducing energy consumption. The fast stabilization technique is implemented in 180nm CMOS process and uses 0.404mm 2 of area. Measurement from test chips shows 50.4μW power consumption during start-up phase with 133x speed gain.
