In this paper, a method of realizing voltage-mode (VM) non-inverting high-pass filter (HPF), band-pass (BPF), low-pass (LPF), and inverting (ILPF) transfer functions structure with two grounded capacitors four resistors through an analytical synthesis is presented. The the VM biquadratic consists voltage proportional block lossless integrators based on use current feedback operational amplifier...

In this paper, we use an adaptive synchronization technique for parameter matching with chaotic persistent excitation (PE). Two Chua’s oscillators, identical in every parameter except for one, are set up in a master/slave configuration where the slave’s mismatched parameter is adaptable. Using a Lyapunov function and incorporating the presence of PE, an adaptive control law is given to ensure e...

Despite excellent high frequency and high speed performance, current-feedback operational ampli ̄ers (CFOAs) generally exhibit poor common-mode rejection (CMRR) properties, which limit their utility [Analogue IC design: The current mode approach, IEE Circuits and Systems Series, Peter peregrinus, 1990]. A novel current feedback operational ampli ̄er (CFOA) with improved performance is presented. ...
