it Trimming circuit for clock source By www.freepatentsonline.com Published On :: Tue, 13 May 2014 08:00:00 EDT A semiconductor trimming circuit includes parallel coupled PMOS devices coupled in parallel with parallel coupled NMOS devices and an additional pair of dummy NMOS devices. The dummy NMOS devices are coupled in parallel with the NMOS devices. A trimming circuit for an internal clock source may be formed with an array of such switches for selecting one or more trimming capacitors of the trimming circuit. Such an array has a low leakage current and permits good trimming linearity. Full Article
it Device having inductor and memcapacitor By www.freepatentsonline.com Published On :: Tue, 14 Oct 2014 08:00:00 EDT Methods and means related to an electronic circuit having an inductor and a memcapacitor are provided. Circuitry is formed upon a substrate such that an inductor and non-volatile memory capacitor are formed. Additional circuitry can be optionally formed on the substrate as well. The capacitive value of the memcapacitor is adjustable within a range by way of an applied programming voltage. The capacitive value of the memcapacitor is maintained until reprogrammed at some later time. Oscillators, phase-locked loops and other circuits can be configured using embodiments of the present teachings. Full Article
