Abstract: A circuit with current-controlled frequency implements a node (2) with an electrical charge which alternatively increases and decreases between two thresholds. The slew rate of the node can be adjusted using a tunable current source (1), thereby enabling tuning of a switching delay. The circuit may be used for controlling the switching frequency of a switch-mode power supply.
