This paper proposes a 12-bit 1MSps SAR ADC(Successive Approximation Register Analog-to-Digital Converter) for SoC(System-on-Chip). The proposed circuit is designed using Magnachip/SK Hynix 0.18㎛ CMOS 1Poly-6Metal process, and it is powered by 1.8 supply. To reduce chip area and power dissipation, we minimized unit capacitor area and number of the total capacitors, and designed the circuit considering optimization as compared to conventional circuits. The proposed circuit in this paper showed high SNDR(Signal-to-Noise Distortion Ratio) of 70.03dB, and excellent effective bit number of 11.34-bit as compared to conventional research results. The designed circuit also showed low power dissipation of 5.5mW, and small chip area of 0.56mm2. The proposed ADC is applicable for the signal conversion of the industry system application.
