Abstract
A curvature-compensation bandgap voltage reference employing current proportional to absolute temperature (PTAT) is presented in this paper. In-package trim for the initial accuracy and temperature coefficient is used to get better performance without extra cost. And the principles and realization of the programmable electrical fuse are discussed in detail, which can be widely used. With the curvature compensation method, simulation temperature coefficient of 15ppm/°C over a wide range of •55°C to +125°C and high initial accuracy of better than 0.1% are achieved. Additionally, this bandgap reference has been embedded in a 16-bit ADC implementation.
