High Toggle Rate High Frequency Analog Switch
By Rust at 3 March, 2010, 9:17 pm
Low impedance gate drive to the 2N3970 analog switch for both on and off drive conditions is provided by this commutator. By producing a low ac impedance for off drive and high ac impedance for on drive to the 2N3970, this commutator circuit can close enough to the ideal gate drive conditions for high frequency [...]
