DESIGN AND ANALYSIS OF SUB 1-V BANDGAP REFERENCE (BGR) VOLTAGE GENERATORS FOR PICOWATT LSI’s
نویسندگان
چکیده
A bandgap reference (BGR) and sub1V BGR circuits for Picowatt LSIs is proposed here. The circuits pertains pico-ampere current reference circuit, a bipolar transistor, and proportional-to-absolute-temperature (PTAT) voltage generators. The circuits neglect resistors and contain only MOSFETs and one bipolar transistor. As the sub-BGR circuit divides the output voltage of the bipolar transistor without resistors, it can operate at a sub1V supply. Experimental results obtained in the 90nm CMOS technology depicts that the BGR circuit could generate a reference voltage of 1.094 V and the sub-BGR circuit could generate one of 0.549 V. The power dissipations of the BGR and sub-BGR circuit corresponds to 8.466 PW and 3023 PW.

We analyze the effects that the Ge profile shape has upon the bias and temperature characteristics of SiGe HBT's. The widely used bandgap reference (BGR) design equation and a more general analytical expression we developed incorporating Ge grading are used to compare silicon devices to their SiGe counterparts. Measurement and simulation show that although the Ge-ramp effect is negligible in th...

The inaccuracy of the analyses commonly used for predicting the temperature behavior of the IcV~ characteristics of transistors and the output of bandgap reference sources is pointed out. The problem is traced to a basic assumption implicit, in such analyses, namely that the variation of the bandgap voltage of silicon with temperature is Iinear; this assumption is shown to be of poor accuracy. ...

This paper discusses the power-supply noise attenuation (PSNA) in the frequency domain of four kinds of bandgap voltage reference that represent the basis of typical voltage references. This performance parameter becomes a fundamental design criterion in high-frequency applications where, due to the reduction in the loop gain, spurious signals coming from the power supply cannot be adequately r...
