This paper presents a novel topology of CCII+ based dual square-and-triangular waveform generator using 3-current conveyors and 5-passive elements, including 2-grounded resistors. The dual square waveform can be used in testing PLL as also in other applications in instrumentation. Simulation using CCII+ and discrete passive components show excellent linearity and tunability both by the resistor and capacitor over the bandwidth of interest (from 5 Hz to 200 kHz). Component sensitivity and temperature sensitivity (over −150° C to +150° C) is next studied. Finally an experimental verification of the proposed design has been tried by realizing the circuit with commercially available CFOA (AD 844 AN) which is next best after ASIC-fabrication. The experimental results are in agreement with the analyses. The topology presents a versatile building block for applications in design of sweep generators for instrumentation, mathematical function generators, and in testing units for ADCs. The design is suitable for ASIC implementation.
