Electronically Tunable Grounded Capacitance Multiplier

New negative‐grounded capacitance multiplier circuits

“…For low frequency applications, mostly higher value capacitance is used that increases the size of capacitor (which requires large area on silicon chip and not suitable from the view point of IC fabrication) 1–3 . Consequently, to alleviate these limitations, researchers and circuit designers have stimulated various positive CMs 4–24 and negative CMs, 25–37 employing different active building blocks. These CMs may find various applications in the design of low frequency filters, low frequency oscillators, and integration of a phase‐locked loop filter 38 .…”
