The authors present two new metal oxide semiconductor field effect transistor (MOSFET)-only second-order voltage and transadmittance-mode band-pass filters (BPFs) employing only five transistors without using any passive elements such as a resistor, a capacitor, and an inductor. As a result, both proposed circuits possess low-power consumption and occupy small chip area. The first proposed filter enjoys low output impedance and offset cancellation for voltage-mode operation while the second proposed filter has low supply voltage. The centre frequency of both proposed filters can be electronically tuned by varying biasing voltage. To demonstrate the performance of the proposed filters, effects of output transconductance of transistors have been investigated and equations of input referred noise have been obtained. Furthermore, fourth-order voltage and transadmittance-mode BPF which is derived the first proposed filter is presented and its simulation results are given. All proposed filters are laid-out in the Cadence environment using Taiwan semiconductor manufacturing company (TSMC) 0.18 µm complementary metal oxide semiconductor (CMOS) technology parameters. The required chip area of the fourth-order voltage and transadmittance-mode band-pass filter is 1100 μm 2 and the power consumption is about 436 µW.

“…When the temperature is set as 300and 373 K, the oscillator frequency is 489 and 405 kHz, respectively, which showsthe change in f o brought about by a 1 K change in T , that is −1.15 kHz/K. This arises from the fact that theparasitic conductance of the CCCII is inversely proportional to the temperature[25].…”

“…This implies that the CCCII, like an operational trans‐conductance amplifier (OTA), is a fundamental, general, and versatile current‐mode device. The CCCII has been extensively used in the realisation of analogue filter, oscillator, and gyrator circuits [12–32]. Unfortunately, most of the oscillator circuits using CCCIIs do not employ a high‐ Q frequency‐selecting network.…”

In this study, a traditional voltage-mode oscillator consisting of a high-Q band-pass filter and a voltage amplifier is transformed into a current-mode oscillator employing a trans-conductance amplifier. Furthermore, a current-mode quadrature oscillator with a high-Q band-pass filter and second generation current-controlled conveyors (CCCIIs) is presented. Since the loop of the oscillator has rich selectivity, the oscillator produces less distortion. Also, the 3 dB bandwidth, oscillation criterion, and oscillation frequency of the oscillator could independently, linearly, and electronically be tuned by the aid of adjusting bias currents of the CCCIIs. Finally, the validity of the designed circuit is verified by means of the computer simulation and the nonideal analysis is performed to explain the results of the simulation. The results show that the designed circuit is workable.
