摘要

A voltage reference, e.g. of bandgap type, for a dense memory includes a frequency compensating capacitor 33 or a low-pass filter 36 to reduce output transients caused by substrate noise. An electrostatic screen may be diffused into the substrate surface to shield high-impedance circuit nodes from the noise, which may be caused by a substrate bias generator. The transient reduction methods allow a lower current consumption. The resistors 26, 27, 29, 31, 34 may be polysilicon. <IMAGE>
