چکیده
A circuit for generating reference voltages for an A/D converter is presented. The circuit consisting of a bandgap reference and a driver circuit is capable of operating on sub 1-volt supply voltages. The circuit is designed using a standard 0.5 m CMOS technology. Simulations show maximum 0.24% variation in the generated reference voltage over a temperature range from -20 C to 100C and a supply voltage range from 0.95 V to 1.50 V. The circuit is capable of driving a 2 pF switched capacitor load at 5 MHz clock rate while consuming 450 W of power from a 1.0 V supply.

متن کاملA High Efficiency Low-Voltage Soft Switching DC–DC Converter for Portable Applications
This paper presents a novel control method to improve the efficiency of low-voltage DC-DC converters at light loads. Pulse Width Modulation (PWM) converters have poor efficiencies at light loads, while pulse frequency modulation (PFM) control is more efficient for the same cases. Switching losses constitute a major portion of the total power loss at light loads. To decrease the switching losses...

متن کاملA High-Temperature, High-Voltage Linear Regulator in 0.8-μm BCD-on-SOI
The sale of hybrid electric vehicles (HEVs) has increased 10 fold from the year 2001 to 2008 [1]. Thus, high temperature electronics for HEV applications are desired in the engine compartment, power train, and brakes where the ambient temperature normally exceeds 150°C. Power converters (i.e. DC-DC converter, DC-AC inverter) inside the HEVs require Gate-Driver ICs to control the power switches....
متن کاملA 100-MS/s 8-b CMOS Subranging ADC with Sustained Parametric Performance
A 100-MS/s 8-b CMOS analog-to-digital converter (ADC) designed for very low supply voltage and power dissipation is presented. This single-ended-input ADC is based on the unified two-step subranging architecture, which processes the coarse and fine decisions in identical signal paths to maximize their matching. However, to minimize power and area, the coarse-to-fine overlap correction has been ...
