Translinear-C Function Generator

A novel function generator is realized using a multi output current controlled current conveyors (MOCCCIIs) based current mode band-pass filter, which can simultaneously provide four phase sinusoidal quadrature current outputs, square and triangular voltage outputs. The circuit basically uses only four MOCCCIIs and four grounded capacitors. The function generator enjoys attractive features such as use of grounded capacitors, wide range electronic tunability, low sensitivity figures and load insensitive current outputs. Moreover due to the absence of external resistors the circuit is very much suitable for monolithic implementation. The proposed function generator is designed and verified with excellent results.
