Abstract：

This　paper　presents　a　sinusoidal　voltage　and　current　generation　integrated　circuit　suitable　for　bioimpedance　measurement.　The　circuit　mainly　consists　of　a　voltage-controlled　oscillator,　a　waveform　conversion　module,　and　a　current　driver.　This　circuit　is　designed　to　generate　a　sinusoidal　current　signal　with　three　adjustable　frequencies,　300　Hz,　1　KHz,　and　3　KHz,　suitable　for　bioimpedance　measurement.　The　sinusoidal　current　generation　chip　is　implemented　in　SMIC　0.18-μm　CMOS　process,　with　a　core　area　of　0.062mm2.　Measurement　results　validate　the　function　of　the　chip.　The　output　voltage　and　current　amplitude　are　140　mV　and　50　nA,　respectively.　The　circuit＇s　power　consumption　is　281　μW,　under　the　power　supply　voltage　of　1.8V.　The　output　frequency　error　is　within　3.3%.　©　2024　IEEE.
