...operation, the noise produced by these high-ΔI/Δt events can be eliminated only by post filtering or a large capacitance. One example of a low-noise charge-pump converter is the MAX850 (Figure 6). Designed to generate very quiet negative bias voltages for GaAsFET RF power amplifiers, it combines an inverting charge pump with a low-noise, negative-output li...
