Abstract: For the first time, this letter proposes a unipolar Schmitt trigger with two transistors structure composed of an antiferroelectric thin film transistor (AFeTFT) and a feedback thin film ...

Sometimes, it is useful to transmit a low-power radio signal to create a beacon, to send a signal carrier to a near receiver, to transmit in QRP or QRPP mode, and so on. The circuit shown here is very ...
