Description
Technical field
The present invention relates to Analogous Integrated Electronic Circuits technical field, specially a kind of filter construction of integrated comparator.
Background technology
The function of present electronic product is more and more, and required chip type is also more and more, and different demands are wanted
Different chips is realized, so the chip on a pcb board is also more and more, but the volume of product is more and more now
It is small.This requires the integrated chip of different function together.
It only requires, by video line transmission video signal, to now desire to transmit controlling by video line before in security protection
Signal controls the purpose of camera to realize.Control signal can only thus be detached by adding a comparator, that
Whole system will more chips, make pcb board area increase.
Invention content
In order to solve the problems, such as that existing CB areas are big, the present invention provides a kind of filter construction of integrated comparator,
The area of pcb board can be effectively reduced.
Its technical solution is such：A kind of filter construction of integrated comparator comprising filter module and compare
Device module, which is characterized in that the filter module and the comparator module integration packaging are described in an integrated chip
There are one Bias circuits, the filter module to be all connected with the Bias electricity with the comparator module for setting in integrated chip
Road is provided with vision signal input pin, vision signal output pin, control signal input tube foot, control in the integrated chip
Signal output pin and reference voltage input pin processed.
It is further characterized by the filter module is difference filter.
After adopting the structure of the invention, filter module and comparator module are integrated in an integrated chip, are shared
One Bias circuit reduces number of devices, peripheral circuits cabling, to greatly reduce the area of pcb board.
Description of the drawings
Fig. 1 is existing filter module；
Fig. 2 is existing comparator module；
Fig. 3 is schematic structural view of the invention；
Fig. 4 is Bias circuit diagrams in the embodiment of the present invention
Fig. 5 is another example structure schematic diagram of the present invention.
Specific implementation mode
See shown in Fig. 3 and Fig. 4, a kind of filter construction of integrated comparator comprising filter module 1 and comparator mould
Block 2, filter module 1 is with 2 integration packaging of comparator module in an integrated chip, and there are one Bias for setting in integrated chip
Circuit 3, filter module 3 electricly connect Bias circuits 3 with comparator module 2, and it is defeated to be provided with vision signal in integrated chip
Enter pin, vision signal output pin, control signal input tube foot, control signal output pin and reference voltage input pin,
3 concrete structure of Bias circuits as shown in Figure 4, in biasing circuit NMOS tube NM2 drain terminal connect comparator module, NMOS tube NM3,
NMOS tube NM4 drain terminals connect filter module.
As shown in Figure 5, filter module can also be difference filter, and connection relation is similar with general filter.
If filter module 1 and comparator module 2 are directly simply packed together, two bias electricity are needed
Road, while the area of chip can become larger, the complexity of circuit can be got higher.And the circuit upper filter module and comparator mould invented
Block shares a bias circuit, optimizes internal circuit configuration, reduces the area of chip.Clamp is clamp voltage electricity in figure
Road.
