	idealised 1:2 step up open loop flyback converter PUBLIC Using the CL transformer to make an idealised 1:2 step up open loop flyback converter. Plots unfiltered primary current showing simulation artifacts and filtered current showing more realistic... by signality \| updated June 26, 2014 flyback flyback-converter
	open circuit switch resistance anomalies 01 PUBLIC The open circuit resistance of switches in CL is not infinite otherwise the intitial voltage across C1 would not be 1V. Simulate > DC Solver > Run DC Solver by signality \| updated May 06, 2014 open-circuit open-circuit-resistance switch switch-resistance
	what is negative inductance? 01 PUBLIC At a fixed frequency, a negative inductance can be seen as a capacitor which presents the same impedance as an inductor but with opposite phase. Simulate > Frequency Domain > Run Frequency-Domain... by signality \| updated March 28, 2014 negative-inductance
	jodes PWS signal source PUBLIC by signality \| updated March 23, 2014
	thermistor beta model PUBLIC Beta model of a ntc thermistor. Includes the effect of self heating. by signality \| updated March 07, 2014 ntc thermistor
	opamp DC gotchas PUBLIC WHATEVER THE BUG WAS IN CL THAT CAUSED THIS PROBLEM: IT NOW SEEMS TO HAVE BEEN FIXED (140202). Beware convergence errors in CL opamp circuits! by signality \| updated February 02, 2014 initial-conditions opamp ramped-supplies sigtorial startup tutorial
	How to draw an arbitrary impedance block (non-simulatable) PUBLIC The name says it all really ... :) by signality \| updated January 24, 2014
	How to set up a sweep to see a hysteresis loop PUBLIC A way to set up a DC sweep to show the hysteresis loop of a schmitt trigger. Not easy to understand but have a play to get your head round it. :) by signality \| updated January 23, 2014 hysteresis schmitt-tirgger
	behavioural non-inverting schmitt trigger 02 (parameterised) PUBLIC Same as: behavioural non-inverting schmitt trigger 01 but with parameters. by signality \| updated January 20, 2014 behavioral behavioural parameters schmitt schmitt-trigger
	3dB down line PUBLIC by signality \| updated January 14, 2014
	Hansen's Active DI Box 02 PUBLIC by signality \| updated January 14, 2014
	current limited DC source PUBLIC A DC source with a current limit. by signality \| updated January 09, 2014 current-limited-source dc-bench-supply
	cunning current source 02 PUBLIC Continuing from cunning current source 01 by signality \| updated January 08, 2014 bench-supply cunning-current-source current-limited-follower current-limited-source current-limited-supply
	cunning current source 01 PUBLIC This produces a voltage follower which has an output that has a current limited pullup of IUP and a pull down of IDN. Simulate > Time Domain > Run Time-Domain Simulation by signality \| updated January 08, 2014 bench-supply cunning-current-source current-limited-follower current-limited-source current-limited-supply
	Charge controlled capacitor demo PUBLIC Demo of the CL charge defined capacitor model. Simulate > Time Domain > Run Time-Domain Simulation by signality \| updated January 03, 2014 variable-capacitor
	CL opamps do not model Vout vs. Iout PUBLIC CL opamps do not model Vout vs. Iout! Simulate > DC Sweep > Run DC Sweep shows that Iout can exceed 100mA. A real TL082 does not do this. Note also that the opamp appears to draw no supply or output... by signality \| updated December 11, 2013
	sample and hold PUBLIC Using back to back MOSFETs to make a sample and hold. signality.co.uk by signality \| updated December 05, 2013 mosfet sample-and-hold
	555 Timer as Astable Multivibrator (Oscillator) model error PUBLIC UPDATE: For a while, around 130723, the CL 555 timer model appeared to now operate correctly but as at 131202, it is broken again as described below. The high level voltage at the OUTPUT pin of the CL... by signality \| updated December 02, 2013 555 astable multivibrator timer
	CL opamps do not model input common mode range PUBLIC CL opamps do not model input common mode range! Simulate > Time Domain > Run Time-Domain Simulation incorrectly shows that Vout still represents the +/-10V difference between two inputs with a 100V... by signality \| updated November 21, 2013 opamp
	Sine and Cosine CL sources 01 PUBLIC Note that to create a cosine from a CL sinusoidal function generator, the phase must be set to -90 degrees. Note also that the output of the cosine source actually starts at zero, i.e: V(cos)=0 at T=0... by signality \| updated November 05, 2013 cosine phase sine sources
