This thesis discusses the theory, circuit design, software design and measurements of an atto-Farad resolution closed-loop impedance measurement bridge circuit for capacitive sensors implemented using commercial off the shelf components.<br/>A lock-in amplifier (LIA) method is used here. The capacitive sensor embedded in an impedance bridge is...
