Single-CDTA (Current Differencing Transconductance Amplifier) Current-Mode Biquad Revisited
This paper presents a current-mode (CM) second-order filter, employing one so-called “Z Copy – Current Differencing Transconductance Amplifier” (ZC-CDTA), two grounded capacitors, and one virtually grounded resistor. The filter provides two current outputs of low-pass (LP) and band-pass (BP) types for driving independent loads, and one high-pass (HP) current output, flowing through one of the w...
متن کاملSymbolic analysis and design of current-differencing-amplifier filters
1) Institut GOŠA d.o.o., Milana Rakića 35, 11000 Belgrade, SERBIA 2) Faculty of Electrical Engineering, Bul. kralja Aleksandra 73, 11120 Belgrade, SERBIA Introduction ANY industrial electronic control systems are designed to operate using only a single-power-supply voltage. The conventional integrated-circuit operational amplifier (IC op amp) is typically designed for split power supplies (±15 ...
متن کاملDesign of Tunable Versatile Filter Using Operational Trans-conductance Amplifier
In this paper, design of a CMOS tunable versatile filter using current conveyor (CC) is presented. The filter is realized at the same time as on the chip is tunable for low pass, band pass, high pass, and elliptical notch filter. The circuit is utilizes two current conveyors, one Operational Trans-conductance Amplifier (OTA), four resistors and two grounded capacitors, ideal for integration. It...
متن کاملDesign of Operational Trans conductance Amplifier in 0.18μm Technology
This paper presents design concept of Operational Transconductance Amplifier (OTA). The 0.18μm CMOS process is used for Design and Simulation of this OTA. This OTA having a bias voltage 1.8 with supply voltage 1.8 V. The design and Simulation of this OTA is done using CADENCE Spectere environment with UMC 0.18μm technology file. The Simulation results of this OTA shows that the open loop gain o...
متن کاملA Novel Adaptive Current Biased Linear Radio-Frequency Power amplifier on SiGe HBT Process
A novel adaptive current biased CLASS-A/shallow AB RF power ampli ̄er is demonstrated in this paper. By theoretical deduction, a prototype is described to improve the linearity of a linear PA. With the realization on Jazz 0:35 m SiGe HBT process and test veri ̄cation, the novel adaptive current biased RF power ampli ̄er shows 3 7 dB improvement of the ACPR at the output power of 19 dBm to meet the...
