This paper presents a Variable Gain Amplifier (VGA) designed in a 0.18 μm CMOS process to operate in an impedance sensing interface. Based on a transconductance-transimpedance (TC-TI) approach with intermediate analog-controlled current steering, it exhibits a gain ranging from 5 dB to 38 dB with a constant bandwidth around 318 kHz, a power consumption of 15.5 μW at a 1.8 V supply and an active area of 0.021 mm2.

Simulation Results

To extend the existing knowledge on first-order voltage-mode all-pass filters, this paper presents two novel first-order voltage-mode all-pass sections, each employing single fully differential second-generation current conveyor (FDCCII) being used as the newly obtained fully differential voltage conveyor (FDVC), a resistor and a grounded capacitor. Both the proposed circuits possess high-input and low-output impedance feature, which makes the proposed circuits ideal for voltage-mode systems. Non-ideal study along with simulation results is given for validation.
