We have a winner for our twelfth Circuit
Challenge.
Congratulations to the randomly selected MrRees, who identified the missing component as a resistor. He wins the £25 Amazon.co.uk voucher.

Figure 2 of this Circuit Design Idea: High-speed op amp enables IR-proximity sensing. The clue was: The circuit shows an amplifier and demodulator. It is part of an IR transceiver that detects the presence of an object and provides an approximate distance.
The circuit schematic-based challenge is dubbed 'One of our components is missing' and you just have to reason which component has been blacked out from a particular (real world) circuit schematic. This month's competition - #13 - is now on the site.
It's just a piece of electronics engineering fun, aimed at those who like reading circuits.
