WebOct 4, 2012 · Simulation has been carried out and the results prove that the PSRR and temperature coefficient (TC) are both improved evidently in low voltage. Under 0.9 V supply voltage, the bandgap reference's PSRR is -86 dB at 1 kHz and -25 dB at 1 MHz, its TC is 0.096 ppm/°C from -40 °C to +85 °C, consuming a total current of 86.6 μA. WebBased on the principle of piecewise compensation, a new high-order curvature compensated method of bandgap reference is presented in this paper. This method focuses on forming multiple local extrema of the curve of reference voltage instead of single valley or peak in the entire operating temperature range, which improves the temperature independence …
