An isolator, circuit, and isolation method are disclosed. An illustrative capacitive isolator is disclosed to include an input side that receives an electrical input signal, an output side that outputs an electrical output signal, and an isolation barrier that electrically isolates the input side from the output side. The input side is further disclosed to include an array of input capacitors, where each capacitor in the array of input capacitors receives an input pulse based on the electrical input signal, where each capacitor in the array of input capacitors receives the input pulse offset from input pulses received at others of the capacitors in the array of input capacitors thereby extending a pulse duration of the electrical input signal.
