“…This device has the advantages of an operational transconductance amplifier, such as the possibility of electronic tuning, and of a differential difference current conveyor (DDCC), such as the possibility of arithmetic operations in voltage mode. Unlike the differential difference transconductance amplifier (DDTA), which has high input and output impedance, the VDDDA is more suitable for voltage-mode operation and filter cascading due to its high input and low output impedance [1][2][3][4][5][6][7][8]. VDDDA has been successfully used in various applications reported in the literature [1][2][3][4][5][6][7][8].…”

“…As mentioned above, the VDDDA CMOS structures in [1,3,5] are standard and not innovative. All VDDDAs [1][2][3][4][5][6][7][8] are incompatible with extremely low supply voltage and low power consumption, which makes them impossible to use in extremely low voltage applications powered by batteries or power harvesting sources.…”

In this paper, a new versatile first-order voltage-mode analog filter using a single multipleinput voltage differencing differential difference amplifier for extremely low-voltage supply and lowfrequency applications is presented. Using multiple-input MOS transistor technique, the filter can realize the first-order transfer functions of non-inverting and inverting low-pass, high-pass, and all-pass filters in a single topology with high input and low output impedance. This is particularly useful for voltage-mode circuits. The filter's pole frequency can be controlled electronically. The filter was used to implement a new quadrature oscillator to confirm its advantages. The multiple-input was applied to bulk-driven differential pairs operating in weak inversion; therefore, the proposed circuit operated from a supply voltage of 0.3 V and consumed 357.4 nW. The circuit was designed in the Cadence program using 0.13 µm UMC CMOS technology. The performance and robustness of the design was validated by intensive simulations, including Monte Carlo and Process, Voltage and Temperature corner analyses.
