-0.6

An n-channel JFET has a pinch-off voltage of V_p = -5V. V_DS(max) = 20V and g_m = 2mA/V. The minimum 'ON' resistance is achieved in the JFET for

$${V_{GS}} = -7V$$ and $${V_{DS}} = 0V$$

$${V_{GS}} = 7V$$ and $${V_{DS}} = 0V$$

$${V_{GS}} = 0V$$ and $${V_{DS}} = 20V$$

$${V_{GS}} = -7V$$ and $${V_{DS}} = 20V$$
