Norfort_voltage_controlled_low_pass_filter
This circuit shows a Norton used as a voltage-controlled low-pass filter, where the 3-dB closed-loop corner frequency is set by ISET input current.Figure 11-16B shows the relationship of ISET and corner frequency. Note that as the compensation capacitor is increased, or ISET is decreased, the maximum slew ratd is decreased.
