“…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].…”

“…In [7], a universal filter based on a compact multiple-input gatedriven CMOS VDDDA structure with a supply voltage of ±0.9 V and a power consumption of 0.99 mW was presented. In [8], an analog current mode VDDDA filter using 32 nm CNTFET technology, conventional CMOS topology with ±0.9 V supply and 166 µW power consumption was used. As mentioned above, the VDDDA CMOS structures in [1,3,5] are standard and not innovative.…”

“…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.

A low-power and compact carbon nanotube field-effect transistor (CNTFET)-based [Formula: see text]-band electronically tunable band-pass filter (BPF) is presented. The filter is designed using second-generation multiple-output current-controlled current conveyor (MOCCCII). The presented active only current-mode BPF employs three MOCCCIIs and two CNTFETs as capacitors. This BPF can be tuned by varying the parasitic resistance of MOCCCIIs via the control current. The designed current-mode tunable BPF is simulated in an advanced design system (ADS) using the Stanford CNTFET model with the extension of noise and manufacturing process variation. The filter achieves a 21–23[Formula: see text]GHz tuning frequency range, with a minimum noise figure of about 11.09[Formula: see text]dB. The 1-dB compression point and input-referenced third-order intercept point are −19.28 and −8.4[Formula: see text]dBm, respectively. This compact filter consumes only 145.7[Formula: see text][Formula: see text][Formula: see text]W power at ± 0.5[Formula: see text]V supply voltage at room temperature. The temperature analysis shows good thermal stability. The Monte Carlo analysis demonstrates the good process variation stability of the filter. The suggested BPF can be thought of as the first fully active BPF that is a candidate for [Formula: see text]-band communication applications with future advances in the fabrication process for CNTFET.
