Singh Raj Senani Division of Electronics and Communication Engineering, Netaji Subhas Institute of Technology, Sector 3, Dwarka, New Delhi, India AJEEE2014264 10.12691/ajeee-2-6-4 2014 09 19 2014 12 08 2014 12 18 One new squaring and two new square-rooting circuits based on CDBAs have been introduced. The new squarer circuit consists of a CDBA, two NMOS transistors and one resistor. On the other hand, the first square-rooting circuit consists of two CDBAs, two NMOS transistors while the second square- rooting circuit consists of only a single CDBA, two NMOS transistors and two PMOS transistors. The proposed circuits exhibit wide input voltage range, very small error and offer low output impedance to facilitate easy cascading without requiring additional buffers. PSPICE simulation results are included which confirm the practical workability of the new circuits.
