Figure 4: Effect of AWG pulse waveform on pump performance for sample 2.
From: Towards a quantum representation of the ampere using single electron pumps
(a) Fractional deviation of pump current from ef in p.p.m., as a function of normalized exit gate voltage at 630 MHz, using sine wave drive (open circles), waveform AWG1 (closed triangles) and waveform AWG2 (closed circles). (b) The three drive waveforms used to obtain the data in panel (a). Dotted line: sine wave, dashed line: AWG1 and solid line: AWG 2. The overall amplitude of the waveforms is ~0.8 Vpp.
