Abstract
An MOS field-effect device which may be fabricated as part of an integrated circuit having the general characteristics of a lowpass filter. A source and drain region define a long channel (e.g. 500 microns or longer). The cutoff frequency of this lowpass filter which is in the audio range, is controllable by the potential applied to a gate member insulated from the channel.
