Obtain maximum value.
Above-mentioned technical proposal of the present utility model has the beneficial effect that：Propose a kind of in such scheme while use big
The circuit of resistance and bulky capacitor, by the way that poly resistance and MIM capacitor are stacked, it is possible to achieve save to greatest extent empty
Between, realize the miniaturization of circuit.In addition, the utility model can be also used for digital television chip and system.
Brief description of the drawings
Fig. 1 uses big resistance and the electrical block diagram of bulky capacitor while being the utility model embodiment；
Fig. 2 is the structural representation of the actual circuit illustrated.
Embodiment
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
The utility model embodiment proposes circuit that is a kind of while using big resistance and bulky capacitor, as shown in Figure 1, institute
It is square, composition MIM capacitor array, and capacitor array edge both vertically as well as horizontally equal average mark to state MIM capacitor unit
Cloth, form square.The poly resistance units are rectangle, and poly is in parallel arranged to form with the long side of the poly resistance of rectangle
Electric resistance array.
Wherein, the width of the poly resistance units of the rectangle is W, minimum poly width wherein in W >=circuit technology, with
Minimum area realizes that resistance maximizes；
Wherein, it is ensured that poly resistance length is more than capacitor array total length, the contact port of both sides is extended MIM electricity
Hold the both sides of array, be easy to resistance line；
Meanwhile the utility model embodiment also proposes bulky capacitor being laminated in design method on big resistive layer, significantly
Chip area is saved.
The utility model embodiment can save area, and do not influence for existing big resistance and the circuit of bulky capacitor
Circuit effect；Especially when the absolute value requirement to electric capacity and resistance is not too strict, this method can save 50% or so
Area.
Fig. 2 be by taking the differential capacitance termination power of a reality as an example, using tsmc1p5m, 0.18um technique, wherein
Poly resistance is about 14.7M Ω * 2, and electric capacity value is 4pF*2.
In tsmc018 techniques, 4pF*2 MIM capacitor needs 16 22um*22um electric capacity in parallel, with perpendicular 3 structures of horizontal stroke 8
Into capacitor array.2 electric capacity are had more used in other circuits.
In tsmc018 techniques, poly resistance minimum widith is 1um, and poly minimum widiths itself are 0.18um, then is taken
Poly wide 0.18um does resistance, greatly promotes resistance value, while reduce area.It will not propose so in certain tsmc rules
Do, but actual flow effect is very good.6 electric capacity length about 147.01um in parallel, resistance unit use length-width ratio for
150um/0.18um poly resistance, 150um length just make the contact port at resistance unit both ends extend in capacitor array
Outside.14.7M Ω * 2 resistance needs about 110 resistance unit series connection, with long side 150um parallel arrangeds, forms electric resistance array.
As shown in Figure 2, by the way that electric resistance array is disposed across under capacitor array in the utility model embodiment, overall electricity
There was only the area of MIM capacitor in road, and all poly resistance are hidden under electric capacity, without extra area occupied, are made whole
Body area occupied is relative to the area that about 50% is reduced without using the method.(resistance is capped in Fig. 2 can not see, only
The MIM capacitor of top layer can be seen.)
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement
The scope of protection of the utility model is also should be regarded as with retouching.
