    This paper presents a principle of analog to digital converter (ADC) based on current mode half flash (BCD). This circuit can be converted to 4-bit output at each moment, and multiple output bit numbers by serial connection. It use a current injection technique to increase the speed of current mirrors, low power and algorithmic ADC application is presented. A current mode, the active current mirror and current comparators that controlled reference current by W/L ratio, has been used. Its feasibility agrees with simulation results of PSPICE program. The circuit design used CMOS 0.5μm which is capable to the slowest conversion time is less than 5.2nS , resulting in a conversion rate of more than 195 MHz , power consumed 1mW , input current 0-60 μA and single 2.5V supply. ©2006 IEEE.
