Programmable Multiphase Sinusoidal Oscillator
A reconfigurable current mode programmable multiphase sinusoidal oscillator is realized using digitally controlled low voltage CMOS current conveyors. The realized current mode programmable multiphase sinusoidal oscillator can provide independent digital control to its oscillating frequency through n-bit control words with high resolution capability, as well as reconfigurability. The realized m...
متن کاملDual-mode Multi-phase Sinusoidal Oscillator with Equal Amplitudes
Article history: Received: 25.12.2014. Received in revised form: 10.3.2015. Accepted: 13.3.2015. This paper presents a current-mode multiphase sinusoidal oscillator (MSO) employing currentcontrolled current differencing units (CCDUs). The proposed oscillator consists of only one CCDU and one grounded capacitor for each phase, and it can generate arbitrary 2n-phase current-output signals (n≥2) w...
متن کاملLog-Domain Current-mode Quadrature Sinusoidal Oscillator
A log-domain current-mode quadrature sinusoidal oscillator based on lossless integrators is presented. The circuit is a direct realization of a first-order differential equation for obtaining the lossy and lossless integrators. Each of the log-domain lossless integrators is realized by using only NPN transistors and a grounded capacitor for achieving low-power and fast response. The proposed os...
متن کاملA High-Frequency Low-Power Low-Pass-Filter-Based All-Current-Mirror Sinusoidal Quadrature Oscillator
A high-frequency low-power sinusoidal quadrature oscillator is presented through the use of two 2-order low-pass current-mirror (CM)-based filters, a 1-order CM low-pass filter and a CM bilinear transfer function. The technique is relatively simple based on (i) inherent time constants of current mirrors, i.e. the internal capacitances and the transconductance of a diode-connected NMOS, (ii) a s...
متن کاملSimulation of a cubic-like Chua's oscillator with variable characteristic
An alternative version of Chua’s oscillator is obtained using a cubic-like nonlinearity [2], which is implemented with two CMOSFET transistors. We propose a modification of this implementation that allows to change the shape of the characteristic in an easy way. A mathematical model of the circuit is derived based on the equations of MOSFET transistors [3] and a Chua’s circuit is simulated usin...
