NOTES
WHILE THIS CIRCUIT IS SIMPLER THAN THE CIRCUIT TO THE RIGHT,
ITS FREQUENCY ACCURACY IS WORSE DUE TO THE EFFECT OF
V+ SUPPLY VARIATION FROM SYSTEM TO SYSTEM AND OVER TEMPERATURE.
NOTES
1. WHEN THE NMOSFET IS OFF, THE FREQUENCY IS SET BY RSET = RSET1.
2. WHEN THE NMOSFET IS ON, THE FREQUENCY IS SET BY RSET = RSET1 || RSET2.
3. V+ SUPPLY VARIATION IS NOT A FACTOR AS THE SWITCHING RESISTOR IS
EITHER FLOATING OR CONNECTED TO GROUND.
