The FM transmitter circuit itself is based off one of [Art Swan]’s builds, but instead of the solderless breadboard construction you would expect to find in a small demo circuit, [Angelo] went ...

Those go to a circuit board he designed which modulates the carrier with the audio signal using a single transistor and then sends the result out the ultrasonic transmitter. He took care to ...

The switch can be enabled or disabled by a special levelshift- up (LSU) circuit. To disable the source termination, the logic high output voltage level from the LSU is applied to the pMOS switch. This ...

The LVDS circuit consists of transmitter (LVDSOUT), receiver (LVDSIN) and bias. The LVDS transmitter consists of a current source (nominal 3.5 mA) that drives the differential pair lines and ...
