Abstract :
A high-output-impedance precision current mirror is implemented in a CMOS dual-output OTA (DOTA) structure by means of an efficient implementation method, which is also applicable to other current-output-based active devices. The new DOTA, when used in a DOTA-C integrator, enables integration at very low frequencies, with a capacitor on the order of several picofarads
