Abstract :
A novel digitally controlled CMOS current follower is proposed. The circuit is useful for low voltage low power high frequency applications. The DCCF operates from a 3 V supply in class AB mode and provides precise digitally programmable current gain without component spread. Experimental results from a 1.2 μm CMOS chip fabricated through MOSIS are provided
