Assignee: DWELLWELL ANALYTICS, INC.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 5:
6. An apparatus comprising:
a capacitor having a capacitor terminal;
a buffer amplifier having an output node;
a first current path between the output node and the capacitor terminal, the first current path having, in series, a first switch and a first diode, the first diode being oriented with a cathode thereof toward the output node;
a second current path between the output node and the capacitor terminal, the second current path having, in series, a second switch and a second diode, the second diode being oriented with a cathode thereof toward the capacitor terminal; and
a first comparator configured to open the first switch in response to a determination that a voltage on the capacitor terminal is above an upper threshold.
