A 0.5V 3.6ppm/C 2.2pW 2-Transistor Voltage Reference
نویسندگان
چکیده
A voltage reference using a depletion-mode device is designed in a 0.13μm CMOS process and achieves ultra-low power consumption and sub-1V operation without sacrificing temperature and supply voltage insensitivity. Measurements show a temperature coefficient of 3.6ppm/C, line sensitivity of 0.033%/V, power supply rejection ratio of -67dB, and power consumption of 2.2pW. It requires only two devices and functions down to Vdd=0.5V with an area of 1350μm. A variant for higher Vout is also demonstrated.

A 0.5V 3-order Tunable gm-C Filter
This paper proposes a 3-order gm-C filter that operates with the extremely low voltage supply of 0.5 V. The employed transconductor is capable for operating in an extremely low voltage power supply environment. A benefit offered by the employed transconductor is that the filter’s cut-off frequency can be tuned, through a dc control current, for relatively large ranges. The filter structure was ...
