"한국 반도체산업의 경쟁력"

IDEC에서 설계인력양성의 발판을 마련하겠습니다.

IP명 A 12 bit Two Step Noise Shaping SAR ADC
Category Analog Application Bio medical IC
실설계면적 3.8㎛ X 1.9㎛ 공급 전압 3.3V
IP유형 Hard IP 동작속도 900MHz
검증단계 Silicon 참여공정 MS180-1902
IP개요 We present a low power ASIC for bio-impedance spectroscopy which performs bio- impedance measurement at several frequencies simultaneously. The system consists of a bootstrapped switch - BS, a dynamic latched comparator, twosegmented Capacitive DAC array, a low power dynamic amplifier, and a noise shaping filter for applying noise shaping technique. The bootstrapped switch sample the input sinusoidal signal to CDAC and prevents the leakage from the CDAC, the dynamic latch comparator with kickback-drinker exactly compares the input differential voltage, and the noise shaping filter filters the final residue voltage and adds to next conversion phase. An FPGA is required for post-processing with MATLAB DSP code.
