With identical integrator, the oscillation frequency would be. The realisability conditions for a true differential integrator now modify to Here we neglect the error products since ; thus. The proposed circuit is shown in Figure 1. By Reanalysis assuming finite quantities, we get a modified transfer equation. Effect of the multiplier device nonideality may be derived by expressing so that we can effectively write for sensitivity calculation, which yields.
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. Semiconductor Product DatabookIntersil Corp.
In this analysis, we neglected the parasitic series resistance? A new single CDBA-based differential integrator with a multiplier element in the circuit loop is presented for obtaining electronic tunability. The quadrature oscillator finds various applications in SSB modulators and spectral phase measurements: The deviation is then computed from the intersection of the function with the real axis of the plot following the Barkhaussen criterion.
Abstract A new dual-input differential input active integrator using a current differencing buffered amplifier CDBA is proposed.

Table ico8013 Contents Alerts. Tuning error and THD measured at three different tuning frequencies. We tested the frequency response of the integrator with antiphase input sinusoid signals and observed the phase error of about 5.
We obtained three such graphs corresponding icl80133 oscillation generation at the nominal frequencies of ? MHzit is possible to obtain an extended frequency range. Albeit other electronically tuned active icl8103 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.
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.
Intersil Datasheet, file dataxheet The frequency stability factor is evaluated by at where is loop phase shift. We therefore get the realisability conditions for a true differential integrator, putting ; dataaheet 4, as here we assumed. KHz in the earlier circuits [ 346 ]. 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.
A multiplier element is appropriately used in the circuit whose control voltage tunes the integrator time constant electronically. The ICL device is a four-quadrant analog multiplier whose output is proportional to the electronic dtaasheet of two input voltage signals with a transmission constant [ 78 ].
The results are shown in Figure 2. The tuning error is then derived as shown in Figure 2 datasheeet and Table 2.

The design of a voltage controlled quadrature oscillator VCQO had then been implemented using the double integrator loop. 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?
The design of a voltage controlled quadrature oscillator VCQO based on the proposed integrator had been satisfactorily implemented. Voltage tunable differential integrator using CDBA-multiplier composite block. 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.
With a nonideal CDBA device, these design equations would alter. The active – sensitivity may be estimated after writing for simplicity, which gives since [ 41112 ]. Subsequently, a double integrator type VCQO had been designed and tested in a frequency range of ? For example, if we assume for a desired at? MHzand improved versatility make it quite suitable for analog signal conditioning and active filter design applications.
The CDBA offers several advantageous features viz. View at Google Scholar A. Embedding the HA multiplier device [ 78 ] with BW ?
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. It may be seen that the select-frequency was reported in the range of a maximum of ?
