Abstract
voltage swing both at the X terminal and at the Z terminal. The VCII consists of a regulated common gate configuration at the Y current input terminal and a class-AB complementary-MOS closed loop output voltage follower that ensures the voltage buffering action between the voltage input X and the voltage output Z terminals. Spice simulation results using AMS 0.35 μm with a ±0.9 V supply voltage are provided to demonstrate the validity of the proposed topology. With a total power consumption of 28 μW, the VCII achieves a voltage swing at the X terminal of ±0.8 V, whereas a ±0.72 V is achieved on the Z terminal. Simulation results for DC and AC voltage and current gains are given, as well as harmonic distortions and noise figures. A final comparison table is also presented, where the proposed VCII is compared with other solutions presented in the literature.File | Dimensione | Formato | |
