Low voltage low power CMOS current mode building blocks for hearing aid applications


Current mode CMOS building blocks for Hearing Aid application are proposed. The proposed circuits include, digital and analog automatic gain controls, digitally controlled Gm-C filters, and a pulse width modulation output stage. The circuits were fabricated in a 2 ?m n-well CMOS process through MOSIS.
