Abstract: A high-voltage-level Miller circuit is employed, with capacitive coupling between the input current source and the amplifying device, and between the output terminal of the amplifying device and the deflection plate being driven. The coupling capacitors and integrating capacitor lie in a feedback loop, which greatly reduces output waveform distortion introduced by these capacitors, permitting the use of much smaller capacitor values. A small grid current provides a low-frequency amplitude constraint which stabilizes the operating point and prevents oscillations which would normally result from the oscillatory phase-shift characteristic produced by the use of the smaller capacitors.
