`
`ABSTRACT
`
`Methods, systems, and apparatuses for down converting a
`modulated carrier signal to a demodulated baseband signal
`are described herein. A first switch is controlled with a first
`control signal Which comprises a first sampling aperture with
`a specified frequency, wherein the first switch is on during the
`first sampling aperture and wherein the first switch is off
`outside the first sampling aperture. A second switch is con-
`trolled with a second control signal which comprises a second
`sampling aperture and wherein the second switch is off out-
`side the second sampling aperture. The first and second con-
`trol signals each control a charging and discharging cycle of
`a respective energy storage element so that for each switch a
`portion of energy is transferred to the respective energy stor-
`age element when the respective switch is on during the
`charging cycle, and a portion of previously transferred energy
`is discharged during the discharging cycle for each respective
`switch when the switch is off. A down-converted in-phase
`baseband signal portion is derived from energy accumulated
`at said first energy storage element during both the charging
`and the discharging cycles for the first energy storage element
`and a down-converted inverted in-phase baseband signal por-
`tion is derived from energy accumulated at said second
`energy storage element during both the charging and the
`discharging cycles for the second energy storage element, and
`the two portions are combined with a first differential ampli-
`fier circuit to form a down-converted differential in-phase
`baseband signal.
