Abstract

This paper presents a single-phase energy measurement IC to measure electric power quantities. The entire IC includes two programmable gain amplifiers (PGAs), two ${\sum}{\Delta}$ modulators, a reference circuit, a low-dropout (LDO) regulator, a temperature sensor, a filter unit, a computation engine, a calibration control unit, registers, and an external interface block. The proposed energy measurement IC is fabricated with $0.18-{\mu}m$ CMOS technology and housed in a 32-pin quad-flat no-leads (QFN) package. It operates at a clock speed of 4,096 kHz and consumes 10 mW in 3.3 V supply.

본 논문에서는 전력 정보를 측정하기 위한 단상 에너지 측정용 IC의 구현 방법을 제안한다. 제안된 전력 측정용 IC는 2개의 PGA(Programmable Gain Amplifier), 2개의 ${\sum}{\Delta}$ modulator, reference 회로, LDO(Low-dropout) regulator, 온도 센서, 필터부, 계산 엔진, 보정 제어부, 레지스터, 외부 인터페이스로 구성된다. $0.18-{\mu}m$ CMOS 공정으로 제작되었고, 32-pin QFN package로 제작되었다. 구현된 IC는 3.3V 전원을 공급받아 동작하며, 동작 클럭 주파수는 4,096 kHz이고, IC 동작시 소비 전력은 10 mW이다.
