`ABSTRACT
`(57)
`Methods, systems, and apparatuses for down-converting a
`modulate carrier signal to a demodulated baseband signal by
`sampling the energy of the carrier signal are described
`herein. Briefly stated, such methods systems, and appara-
`tuses operate by receiving a modulated carrier signal and
`using pulses with apertures to control a switch so as to (a)
`transfer energy from the modulated carrier signal and accu-
`mulate the transferred energy in a capacitor when the switch
`is closed during the apertures of the pulses and (b) discharge
`some of the previously accumulated energy from the capaci-
`tor into load circuitry at least when the switch is open. The
`demodulated baseband signal is generated from (i) accumu-
`lating energy transferred to the capacitor each time the
`switch is closed during the apertures of the pulses, and (ii)
`discharging some of the previously accumulated energy into
`the load circuitry each time the switch is opened.
