| Abstract: | This paper presents a low voltage low power operational transconductance amplifier circuit. By using a source degeneration technique, the proposed realization powered at ±0.9 V shows a high DC gain of 63 dB with a unity gain frequency at 3.5 MHz, a wide dynamic range and a total harmonic distortion of ?60 dB at 1 MHz for an input of 1 Vpp. According to the connection of negative current terminal to positive voltage terminal of double output OTA circuit, a second generation current conveyor (CCII-) has been realized. This circuit offers a good linearity over the dynamic range, an excellent accuracy and wide current mode of 56 MHz and voltage mode of 16.78 MHz cut-off frequency f-3 dB.Thereafter, new SIMO current-mode biquadratic filter composed by OTA and CCII as active elements and two grounded capacitors is implemented. This filter is characterized by (i) independent adjusting of pole frequency and quality factor, (ii) it can realize all simulations results without changing the circuit topology, (iii) it shows low power consumption about 0.24 mW. All simulations are performed by Cadence (Cadence Design Systems) technology Tower Jazz 0.18 μm TS18SL. |
