Abstract (en)
[origin: WO9966639A1] A current-controlled output buffer circuit includes a control circuit (110), a charging circuit (120), and a discharging circuit (150). The control circuit is configured to receive a control signal (102), and in response produces a charging signal (106) and discharging signal (108). The charging circuit is configured to receive the charging signal and in response, supplies a charging current to an output terminal, the magnitude of the charging current producing a signal rise time. The discharging circuit is configured to receive the discharging signal and in response, sinks a discharging current from the output terminal, the magnitude of the discharging current from producing a signal fall time.
