Abstract :
A U-interface line driver for a single-chip ISDN (integrated services digital network) NT (network termination) in an advanced 3.3-V, 0.5-μm CMOS technology is presented. It features a THD (total harmonic distortion) better than -68 dB for an output swing of 5 Vpp on a 67-Ω load in a band up to 60 kHz. A novel quiescent current control circuit is implemented. The advantages of this new approach lie in the reduction of the variation of the quiescent current and the facilitation of the driver´s circuits and compensation scheme
