	Logarithmic amplifier PUBLIC Standard log-amp design. Modified so both negative and positive signals will be processed. by anubi | updated June 02, 2012 amplifier   analog   level-shift   op-amp
	Howland Current Source PUBLIC Classic Howland Current Source by anubi | updated May 23, 2012 constant-current-source   current-regulator   op-amp
	Differential FET-BJT Amplifier PUBLIC Stripped down version of "Geophone amplifier". by anubi | updated May 20, 2012 amplifier   audio   bias-point   bjt   jfet   level-shift
	differential FET/BJT amp 2 PUBLIC Differential FET input, single supply, referenced to ground. V6 or R13 sets bias point. Differential in. Differential out. Note Q1, Q2 feed back through Q5E to improve CMRR and stabilize bias over... by anubi | updated May 20, 2012 amplifier   audio   bjt   differential   jfet
	Geophone Amplifier PUBLIC Single-supply voltage. High-impedance differential input referenced to ground. Low impedance differential line-driver output. This circuit would not converge with old JFET model. CircuitLab fixed the... by anubi | updated May 19, 2012 amplifier   audio   bjt   differential   jfet   level-shift   startup
	Trouble2 PUBLIC This is a subset of "Trouble 1". This is the core voltage gain and DC bias feedback which would exhibit convergence difficulty on the old FET model. CircuitLab has fixed the model. This circuit now... by anubi | updated May 18, 2012 amplifier   bjt   convergence   feedback   initial-conditions   jfet   level-shift   startup
	servo amp 2 PUBLIC An extension of servo amp 1. Note dead zone insures no "shoot through" or "cross conduction". For bi-directional motor drive or thermoelectric cooler drive. by anubi | updated March 22, 2012 h-bridge   level-shift   motor   power   servo
	servo amp 1 PUBLIC Drives high power loads with small control voltage. Note "dead zone" near zero. This is to eliminate "shoot thru" and guarantee both transistors can not on simultaneously. Not recommended for audio... by anubi | updated March 22, 2012 motor   power   servo
