—Design and simulation of a digitally controlled CMOS fully differential current conveyor (DCFDCC) is presented. A novel current division network (CDN) is used to provide the digital control of the current gain between terminals and of this DCFDCC. The proposed DCFDCC operates under low supply voltage of 1 5 V. The realization of the DCFDCC using the new(More)
A new CMOS voltage controlled balanced output transconductor (BOTA) is introduced. Application of the CMOS BOTA in realizing mixed-mode filter implementation featuring electronic tunability is presented. The filter realizes second order lowpass, bandpass, highpass, allpass and notch responses. The proposed filter architecture uses grounded capacitors and(More)
— a novel CMOS low-voltage current feedback operational amplifier (CFOA) is presented. The proposed CFOA based on a new positive second-generation current conveyor (CCII+). The new circuit allows almost a rail-to-rail input and output operation; also, it reduces the offset voltage and provides high driving current capabilities. The CFOA is operating at(More)
proposed configurable analog block (CAB) is presented, simulated and analyzed. The CAB consists of a CMOS current feedback operational amplifier (CFOA), presented by the authors, as the main active block, programmable resistor array, programmable capacitor array and MOSFET switches. Using the CABs, the universal field programmable analog array (FPAA) has(More)
A digitally controlled balanced output transconductor (DCBOTA) is proposed and analyzed. The proposed DCBOTA is based on the BOTA given in Ref. 1 and MOS switches. The DCBOTA transconductance is tunable in a range of 2 n−1 times using n bits control word. The proposed DCBOTA is simulated using CMOS 0.35 µm technology and the results have shown the(More)
