This paper presents 1V supply voltage Bi-CMOS current mode circuits. The circuits are consist of current mirrors, current comparators and current sources. The circuits have some advantages such as high accuracy, high speed, high density and low power supply. As an application of the circuits, an analog-to-digital converter (ADC) is given. The ADC operates with small chip area and low power dissipation. The performances of the proposed circuits were confirmed by using SPICE2 simulation.
