Photo transistor gain
WebTransistors can give us 20 to 50 db of gain, depending upon the type, while consuming less than two milliwatts of power. The junction type TRANSISTORS are about 10 times more efficient than the point contact type for small - signal amplification. The TRANSISTOR has no filament so there are no problems of filament burn-out. WebMay 7, 2024 · In this configuration the Darlington Transistor provide high gain ability. As usual the LED emits infrared led and controls the base of the pair transistor. This type of opto-coupler also used in DC circuit related area for the isolation.

Go for a detector with a large surface area to gather more light perhaps (more signal for the same amount of noise).
WebJan 19, 2024 · These enhancement effects are owing to the internal gain of the phototransistor. The fabricated phototransistor exhibits a high photoresponsivity ( R ) of 2.16 × 10 4 A/W and a detectivity ( D *) of 9.63 × 10 11 jones, with gate voltage ( V G ) and drain voltage of approximately -1.5 V and -5 V, respectively, under 213 nm light illumination. WebIf the GBWP of an operational amplifier is 1 MHz, it means that the gain of the device falls to unity at 1 MHz. Hence, when the device is wired for unity gain, it will work up to 1 MHz (GBWP = gain × bandwidth, therefore if BW = 1 MHz, then gain = 1) without excessively distorting the signal.
