A New Method to Synthesise the Sinusoidal Oscillator Based on Series Negative Resistance-Capacitance and its Implementation Using a Single Commercial IC, LT1228

An alternative method for synthesising the sinusoidal oscillator based on series negative resistance-capacitance is presented in this paper. The proposed topology constructed with circuit connected parallel a grounded resistor and capacitor. To validate method, new simulator also as subcircuit oscillator. commercially available integrated (IC), LT1228. equivalent resistance capacitance can be adjusted electronically using an external DC bias current. that synthesised consists of single LT1228, two capacitors, three resistors. frequency condition oscillation are orthogonally adjusted. Also, controlled. amplitude waveform adjustable. In addition, output voltage node has low impedance, which allows it to connect other circuits without additional buffer. Both PSPICE simulation experiment used circuits.
