capacitor charging from V

SS
(the ALGRC pin charges from V
DD
to V
SS
through a resistor). The
capacitor will charge rapidly via a charge switch after ALGO returns low. To obtain unequal present
and absent guard times, a diode can be connected as shown in Figure 7-6, to give the unequal
resistance required during capacitor charging and discharging.
