The proposed circuit is shown in Figure 1. The results are shown in Figure 2.

The quadrature oscillator finds various applications in SSB modulators and spectral phase measurements: MHzit is possible to obtain an extended frequency range. The active – sensitivity may be estimated after writing for simplicity, which gives since [ 41112 ].

In this analysis, we neglected the parasitic series resistance? Embedding the HA multiplier device [ 78 ] with BW ? We therefore get the realisability conditions for a true differential integrator, putting ; to 4, as here we assumed.

The deviation is then computed from the intersection of the function with the real axis of the plot following the Barkhaussen criterion. The CDBA offers several advantageous features viz.

In order to examine the tuning error in we had carried out a new type of measurement using the Nyquist plot of the loop transfer function of the double-integrator loop in the vicinity of as shown in Figure 2 d.

A new single CDBA-based differential integrator with a multiplier element in the circuit loop is presented for obtaining electronic tunability. We obtained three such graphs corresponding to oscillation generation at the nominal frequencies of ?

Voltage tunable differential integrator using CDBA-multiplier composite block. With 2 in 1an ideal dual-input integrator function is obtained as where if then with Hence the time constant is electronically tunable for the range? Inspection of 7 indicates the realisability of high quality integration where may be preset to a high value byand sets the realisability while tunes electronically and independently.

After putting we obtained since we selected.

Active and Passive Electronic Components. Intersil Datasheet, file number The ICL device is a four-quadrant analog multiplier whose output is proportional to the electronic product of two input voltage signals with a transmission constant [ 78 ].

The realisability conditions for a true differential integrator now modify to Here we neglect the error products since ; thus. The CMRR had datashert measured to be 96? Analysis The proposed circuit is shown in Figure 1. KHz in the earlier circuits [ 346 ]. MHz with a typical set of values?

It may be mentioned here that one can select any of the two default values of the multiplier constant and for the ICL multiplier device [ 7 — 91314 ] in order to enhance the tuning range concomitantly while keeping and as the limit. The design of a voltage controlled quadrature oscillator VCQO had then been implemented using the double integrator loop.

MHz with suitable design. We design a VCQO using the proposed integrator in a two integrator loop, each being used single ended, one inverting and the other in noninverting mode, that is, from 3 we designed andthereafter cascading the two integrators in a loop. The frequency stability factor is evaluated by at where is loop phase shift. Subsequently, a double integrator type VCQO had been designed and tested in a frequency range of ?

Tuning error and THD measured at three different tuning frequencies. The responses had been measured for a range of ? The tuning error is then derived as shown in Figure 2 e and Table 2. With a nonideal CDBA device, these design equations would alter. The device imperfections may be expressed in terms of some port mismatch ratios [ 2 — 4 ] given by the relations The and terminals of the CDBA however are internally grounded; hence In the literature, the mismatch ratios are postulated in terms of some low-magnitude error [ 2 — 6 ] quantities given byand for an ideal device the errors vanish.

For example, if we assume for a desired at? It may be seen that the select-frequency was reported in the range of a maximum of ? We tested the frequency response of the integrator with antiphase input sinusoid signals and observed the phase error of about 5. Table of Contents Alerts.

Indexed in Web of Science. A new dual-input differential input active integrator using a current differencing buffered amplifier CDBA is proposed. The design of a voltage controlled quadrature oscillator VCQO based on the proposed integrator had been satisfactorily implemented. Semiconductor Product DatabookIntersil Corp.

Datasheeets & Application Notes

The nodal equations characterizing an ideal CDBA element are [ 1 ]. With identical integrator, the oscillation frequency would be. We propose here a new electronically tunable differential integrator using a CDBA; the control voltage of a multiplier element, incorporated suitably in the circuit, tunes electronically. View at Google Scholar A. Albeit other electronically tuned active realisations were reported recently in relatively lower frequency-range using CFA [ 14 ], current conveyors [ 1516 ], or OTA-based allpass filter [ 17 ], such a function circuit using the CDBA had not yet been presented.

A multiplier element is appropriately used in the circuit whose control voltage tunes the integrator time constant electronically.
