6 Tx Detailed Schematic Astable configuration See Design Example Lowside switch with current limiting A. Kruger IR Link Labs, Version 2.3 6

7 Tx Current Limiting MOSFET is used as a switch. Drive V G >> V TN to turn it on hard When the voltage here (I D R limit ) reaches 0.7 V, then the BJT turns on and clamps V G, thus limiting further increase in I D This resistor limits I C so that the BJT is not destroyed.

29 Detector Buffer We will use a phototransistor rather than a photodiode. Phototransistors are times more sensitive than photodiodes, but are nonlinear and slower. However, in this application these factors are less important. converts the photo current (few A to small (~ mv) voltage. The larger, the bigger the photovoltage, so for sensitivity one wants it to be large. However, increasing also increases the dc photo current and dc voltage across it. If it is made too large, the dc voltage across it will approach the power supply. Start with a value = 10K, and once the complete receiver works, come back and adjust its value. The coupling capacitor blocks dc. It forms a time constant with and the input resistance of the buffer stage. One can use this to filter out 120 Hz noise. A. Kruger IR Link Labs, Version

30 Detector Buffer Use a 2N7000 MOSFET configured as a source follower as a buffer. The buffer will have a voltage gain < 1, but can have a very high input resistance. This is important because we don t want to load. Since ~ 10K, design the source follower so that its input resistance is much larger. We want the source follower s output impedance small so that the source follower can drive the subsequent gain block. The gain block s input resistance is on the order of 2.5K. The follower s output resistance should be much smaller than this. Note that the follower s output resistance depends on and. Additionally, we want the dc voltage across to be roughly midway between the power supply rails. This allows for the output voltage to swing symmetrically before being clipped. Start the design by picking a reasonable. A. Kruger IR Link Labs, Version

31 Buffer Gain Block Use a 2N2222 BJT for the gain block. We want the dc voltage across to be roughly midway between the power supply rails. This allows for the output voltage to swing symmetrically before being clipped. Start the design by picking a reasonable. Choose so that it is a short at the operating frequency (5 khz). The coupling capacitor sees the output resistance of the follower and the input resistance of the gain block and forms a time constant. One can design for to provide additional filtering to pass the 5 khz signal and suppress the 120 Hz noise. A. Kruger IR Link Labs, Version
