Frequently frequency signal can linearly be transferred to voltage signal by pressure converter, and the magnitude of voltage of output is in direct ratio with pulse frequency
Linear relationship, the design uses frequency/voltage conversion circuit to turn 0-10V conversion to realize 0-10KHz, and circuit is as it is shown on figure 3, be by transporting
Calculate amplifier A1, the frequency/voltage conversion circuit of A2, A3 composition.A1 constitutes hysteresis loop comparator, and input has diode VD1, VD2 amplitude limit
Protection, A1 converts input signals into the square-wave signal that frequency is identical, then rises narrow arteries and veins through differential capacitance C1 and diode VD3
A2 is delivered in punching.A2 constitutes monostable circuit, and under normality, its anti-phase input Un is nagative potential, and making input is high level, and V1, V2 lead
Logical, at this moment U2 is low level.Positive triggering pulse makes N2 overturn rapidly output low level, and V1 ends, and U2 rises to high level, it etc.
In voltage stabilizing value Um of stabilivolt VS1, Un keeps high level Uh.V2 cut-off, makes C be charged by R, through the Tw time, on Up simultaneously
Being raised to more than Uh makes N2 again overturn RESET, and monostable process terminates.By U2, export fixed width (Tw), the pulse of tentering degree (Um),
The frequency of U2 output high level increases with the rising of incoming frequency.Can be calculated by the fundamental formular of RC Circuit Transient
It is Tw=R*C*ln [(R1+R2) * E/ ((R1+R2) * E-(R1*Um-R2*E))] * that RC charges to the charging interval used of high level
R/(R+R6).N3, R12 and C2 constitute low pass filter, and output voltage average value is Uo=Tw*Um*Fi；In circuit, R1 takes 200K,
R2 takes 100K, C and takes 0.1 μ F, and it is all 5V that R takes 10K, E and Um, can obtain Tw=0.2ms.Can be by 0-10KHz linear transformation 0-10V.

Level, V2 constitutes circuit output stage.Ub is bias voltage, in order to carry out zero-bit translation.Owing to circuit uses current parallel negative feedback,
There is preferable constant current performance.
Utilize principle of stacking, can obtain under the effect of Ui, Ub and output electric current Io, the in-phase input end of operational amplifier
With anti-phase input terminal voltage Up and Un.When considering only input voltage Ui effect, because of R3 > > RL, therefore have Una ≈ R3*Ui/ (R1+
R3).Consider Unb ≈ R1*RL*Io/ (R1*R3), Upa ≈ R2* (RL+R7) * Io/ (R2+ during the effect of only output electric current Io
R4).Under Ub effect, because of R4 > > RL+R7, Upb ≈ R4*Ub/ (R2+R4).The open-loop gain of operational amplifier and input resistance
