Log-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...

This paper presents a new Current Differencing Transconductance Amplifiers (CDTA)based resistorless current-mode Quadrature Oscillator (QO). The proposed QO consist of two CDTAs and two grounded capacitors, and it is completely resistorless, which are suitable for monolithic integration. The QO can provide two explicit quadrature outputs at high impedance terminals, which are convenient for cas...
متن کاملSimple quadrature oscillator for BIST∗
In this letter, a simple quadrature oscillator for built-in self-test (BIST) of integrated analog filters is proposed. A new hardware-efficient approach for amplitude control is described, with as main assets: (i) the technique requires little hardware which makes it very useful for BIST, (ii) the oscillation amplitude is well defined, and (iii) the distortion-level introduced by the amplitude ...
