An Implementation of Differential Difference Voltage Difference Transconductance Amplifier (DD-VDTA) and Its Application as a Dual Output Integrator

This research article brings a design of Differential Difference Voltage Difference Transconductance Amplifier (DD-VDTA), which enables the Differential Difference property in a traditional VDTA block. It can be achieved by adding Differential Difference Amplifier (DDA). The verification of the DD-VDTA block is first verified with both DC and AC characteristics using PSPICE simulation. Moreover, the applications of this block is extended for the design of lossy inverted and non-inverted integrator and lossless integrator. The workability test of the DD-VDTA-based dual output inverted and non-inverted integrator is well simulated in PSPICE.
