Hi

I need suggection for the circuit with following requirements :
- Circuit should withstand against dark current fluctuations from photodiode and maintain its output .
- low OFF current (no more 5 uA)
- low voltage (2 - 4 V)
- Switch ON slew rate max 3 usec
- Switch OFF slew rate amx 10 usec
- Temperature range -30 - 75 C
- Price no more than 20 cents
- Output OFF voltage 0.6 * Vcc
- Output ON voltage 0.2 * Vcc
- ON current pulse duration max 30 usecs

OFF when there is no current into amplifier

Below is the draft circuit i designed to meet these criterias .

Is it possible to further decrease its price and components ?
