Method for measuring transconductance |
摘要 |
A method for measuring transconductance of an oscillating circuit is provided. The oscillating circuit includes an inverter. When an input terminal and an output terminal of the inverter are floated, the bias voltage of the inverter is obtained by measuring the output terminal thereof. Based on floating the input terminal and respectively providing a first voltage and a second voltage to the output terminal, a first current corresponding to the first voltage and a second current corresponding to the second voltage are measured from the output terminal. The first voltage and the bias voltage have the same voltage levels. An output resistor value of the inverter is obtained according to the first and second voltages and the first and second currents. The transconductance of the oscillating circuit is obtained according to the output resistor value. |
