Current mode single resistance controlled oscillators using only grounded passive components

Voltage-mode quadrature sinusoidal oscillator with current tunable properties

“…If these realizations are used as single frequency oscillators, then electronic control can be used to tune the frequency to the desired fixed frequency which varies with PVT variations. The presence of quadrature voltage signals is another important feature which is not pointed/discussed in [7][8][9][10] (though possible in many two integrator based SRCOs). Although, the availability of quadrature voltage signals was discussed in [23] (see, Eq.…”

“…It is worth mentioning that such electronic control is not inherently available in any conventional current-conveyor (CC) (or CC variant) based 3R-2C single-resistance-controlled oscillators (SRCOs) (see [6][7][8][9] and references cited therein). The entire family of differential difference current conveyor (DDCC) [10] based 3R-2C SRCOs in [11,12] use two DDCCs and one of the DDCC has two of its input y terminals grounded (and hence unused!).…”

High Performance Temperature Insensitive Current Mode Rectifier without Diode

“…The circuit using current mode techniques has proved its advantage in many applications, like linear circuits such as active filters and non-linear circuits also such as relaxation oscillators, triggers, and precision rectifiers [2][3][4][5][6]. The main advantages of the current-mode circuits are wide dynamic range of frequency, good linearity over the full operational range, low temperature sensitivity, and low power supply voltages requirement etc.…”

Electronically Controllable Explicit Current Output Sinusoidal Oscillator Employing Single VDTA

“…Sinusoidal oscillators find numerous applications in communication, control systems, signal processing, instrumentation, and measurement systems; see [3][4][5] and the references cited therein. Explicit current-mode sinusoidal oscillators (ECMSOs) based upon different active single building blocks are available in the literature; see [6][7][8][9][10][11][12][13] and the references cited therein.…”
