N2 - A low power design of CMOS bandgap reference of current mode used in analog-to-digital converter is proposed to obtain stable reference current and voltage. It realizes low power by one-order temperature compensation, resistance startup block, optimized internal operational amplifier and a new designed reference voltage buffer instead of closed loop. Under SMIC CMOS 0.35um 1P6M process and simulated by Spectre in Cadence, the circuit offers the current output of 50uA and the voltage output of 0.95V, 2V and 2.6v with a temperature coefficient of 50×10-6°C-1 in the range of -40∼125°C. With the 3.3V supply, the power in test is lower than 0.2mW.
