A Novel Design of Tunable and Balanced VDIBA

A novel design of tunable & balanced voltage differencing inverting buffered amplifier (VDIBA) is presented in this paper. The presented design is symmetric and employ dual current sources to develop a balanced circuit instead of a single current source used in conventional VDIBA designs. The operation of the presented VDIBA is exhibited through detailed analyses. To illustrate the application of the presented VDIBA circuit, a high-pass filter configuration is designed. The power consumption and transconductance of the presented VDIBA design are 17.4 mW and 614 mS respectively. The presented VDIBA is designed and simulated using 45 nanometer CMOS process in Cadence at ±1 V supply voltage.
