Abstract :
A capacitance multiplier circuit, using operational transconductance amplifiers, is realised. The circuit provides widerange linear control of the capacitance value with direct voltage or current. This makes the realisation of large-valued grounded capacitors possible in IC fabrication. The linearly tunable capacitor is expected to find attractive applications in voltage/current-controlled filters, oscillators etc.
