This paper presents a new CMOS current feedback operational amplifier (CFOA) with rail to rail swing capability at all terminals. The circuit operates as a class AB for lower power consumption. Besides operating at low supply voltages of AE 1.5 V, the proposed CFOA has a standby current of 200 "A. The proposed CFOA circuit is thus a versatile building block(More)
—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)
A novel low-voltage CMOS current feedback operational amplifier (CFOA) is presented. This realization nearly allows rail-to-rail input/output operations. Also, it provides high driving current capabilities. The CFOA operates at supply voltages of ±0.75 V with a total standby current of 304 µA. The circuit exhibits a bandwidth better than 120 MHz and a(More)
This paper presents a novel CMOS low-voltage and low-power positive second-generation current conveyor (CCII +). The proposed CCII + uses two n-channel differential pairs instead of the complementary differential pairs; i.e. (n-channel and p-channel), to realize the input stage. This solution allows almost a rail-to-rail input and output operation ; also it(More)
The increasing growth in the use of electronic equipment in recent years has resulted in a greater need to ensure that the line current harmonic content of any equipment connected to the ac mains is limited to meet regulatory standards. This requirement is usually satisfied by incorporating some form of Power Factor Correction (PFC) circuits to shape the(More)
