  • Patent number: 11520962
    Abstract: Techniques and systems for determining an output waveform at an output of a complementary metal-oxide-semiconductor (CMOS) logic gate are described. Some embodiments can identify at least one set of inputs of the CMOS logic gate that, when switched together, causes multiple transistors coupled in parallel to simultaneously turn-on and drive the output of the CMOS logic gate. Next, the embodiments can determine a set of current source models that are coupled in parallel to model the CMOS logic gate when the set of inputs of the CMOS logic gate are switched together. The embodiments can then simulate the set of current source models together to determine the output waveform at the output of the CMOS logic gate when the set of inputs of the CMOS logic gate are switched together.

  • Patent number: 11410842
    Abstract: Apparatus and method for processing an image-charge/current signal for an ion(s) undergoing oscillatory motion within an ion analyser apparatus. The method comprises: obtaining a recording of the image-charge/current signal (20a-20e) in the time domain. Then, by a signal processing unit, a value for the period (T) of a periodic signal component is determined within the recorded signal. Subsequently, the recorded signal is segmented into a number of successive time segments [0;T] of duration corresponding to the period (T). These lime segments are then co-registered in a first time dimension (t1) defining the period (T). The co-registered time segments are then separated along a second time dimension (t2) transverse to the first time dimension (t1). This generates a stack of time segments collectively defining a 2-dimensional (2D) function. The 2D function varies both across the stack in the first time dimension and along the stack in the second time dimension.
