2-phased inverter pump
Phase 1
Please refer to figure below: In the first phase of the clock cycle, switches S2 and S4 are opened and S1 and
S3 closed. This connects the flying capacitor, C3, from Vin to ground. C3 charge up to the input voltage
applied at Vcc.
Phase 2
In the second phase of the clock cycle, switches S2 and S4 are closed and S1 and S3 are opened. This
connects the flying capacitor, C3, in parallel with the output capacitor, C
VSS2
. The Charge stored in C3 is
now transferred to C
VSS2
. Simultaneously, the negative side of C
VSS2
is connected to V
SS2
and the positive
side is connected to ground. With the voltage across C
VSS2
smaller than the voltage across C3, the charge
flows from C3 to C
VSS2
until the voltage at the V
SS2
equals -V
