lmh6642q-q1 , lmh6643q-q1 www.ti.com snosc61c ? january 2012 ? revised september 2014 8.2 single supply, low power photodiode amplifier the circuit shown in figure 57 is used to amplify the current from a photo-diode into a voltage output. in this circuit, the emphasis is on achieving high bandwidth and the transimpedance gain setting is kept relatively low. because of its high slew rate limit and high speed, the lmh664x family lends itself well to such an application. this circuit achieves approximately 1v/ma of transimpedance gain and capable of handling up to 1ma pp from the photodiode. q1, in a common base configuration, isolates the high capacitance of the photodiode (c d ) from the op amp input in order to maximize speed. input is ac coupled through c1 to ease biasing and allow single supply operation. with 5v single supply, the device input/output is shifted to near half supply using a voltage divider from v cc . note that q1 collector does not have any voltage swing and the miller effect is minimized. d1, tied to q1 base, is for temperature compensation of q1 ? s bias point. q1 collector current was set to be large enough to handle the peak-to-peak photodiode excitation and not too large to shift the u1 output too far from mid-supply. no matter how low an r f is selected, there is a need for c f in order to stabilize the circuit. the reason for this is that the op amp input capacitance and q1 equivalent collector capacitance together (c in ) will cause additional phase shift to the signal fed back to the inverting node. c f will function as a zero in the feedback path counter- acting the effect of the c in and acting to stabilized the circuit. by proper selection of c f such that the op amp open loop gain is equal to the inverse of the feedback factor at that frequency, the response is optimized with a theoretical 45 phase margin. where gbwp is the gain bandwidth product of the op amp (1) optimized as such, the i-v converter will have a theoretical pole, f p , at: (2) with op amp input capacitance of 3pf and an estimate for q1 output capacitance of about 3pf as well, c in = 6pf. from typical performance characteristics , lmh6642/6643 family gbwp is approximately 57 mhz. therefore, with r f = 1k, from equation 1 and equation 2 above. c f = 4.1 pf, and f p = 39 mhz figure 57. single supply photodiode i-v converter copyright ? 2012 ? 2014, texas instruments incorporated submit documentation feedback 23 product folder links: lmh6642q-q1 lmh6643q-q1 + - v bias c d 10 - 200pf photodiode r d c1 100nf q1 2n3904 r5 510 : r2 1.8k : d1 1n4148 r3 1k : r11 910 : r10 1k : -1ma pp c f 5pf r f 1k : v cc = +5v r bias photodiode equivalent circuit i d 100k : v out +5v x sqrt gbwp/(2 s r f ? c in ) f p = c f = sqrt (c in )/(2 s? gbwp ? r f )
lmh6642q-q1 , lmh6643q-q1 snosc61c ? january 2012 ? revised september 2014 www.ti.com single supply, low power photodiode amplifier (continued) for this example, optimum c f was empirically determined to be around 5pf. this time domain response is shown in figure 58 below showing about 9 ns rise/fall times, corresponding to about 39 mhz for f p . the overall supply current from the +5 v supply is around 5 ma with no load. figure 58. converter step response (1v pp , 20 ns/div) 8.3 printed circuit board layout and component values section generally, a good high frequency layout will keep power supply and ground traces away from the inverting input and output pins. parasitic capacitances on these nodes to ground will cause frequency response peaking and possible circuit oscillations (see application note oa-15 ( snoa367 ) for more information). texas instruments suggests the following evaluation boards as a guide for high frequency layout and as an aid in device testing and characterization: device package evaluation board pn lmh6642qmf 5-pin sot-23 lmh730216 lmh6643qmm 8-pin vssop lmh730123 another important parameter in working with high speed/high performance amplifiers, is the component values selection. choosing external resistors that are large in value will effect the closed loop behavior of the stage because of the interaction of these resistors with parasitic capacitances. these capacitors could be inherent to the device or a by-product of the board layout and component placement. either way, keeping the resistor values lower, will diminish this interaction to a large extent. on the other hand, choosing very low value resistors could load down nodes and will contribute to higher overall power dissipation. 24 submit documentation feedback copyright ? 2012 ? 2014, texas instruments incorporated product folder links: lmh6642q-q1 lmh6643q-q1 200 mv/div 20 ns/div
