eSketch 2.05

eSketch 2.05 brings about a handy and robust schematic capture and simulation application which is aimed at the ultra fast rendition and simulation of frequency-shaping analog circuits such as preamplifiers, amplifiers, active filters, passive filters, crossovers, equalizers and tone controls. eSketch is a specialized program for circuits containing capacitors, inductors, resistors and op amps. It does not provide transistors, diodes or other non-linear devices.

The programs simplicity of use and speed of execution provide an "electronic sketching" environment in which the effects of changes in layout, component values, component tolerances and op amp Gain Bandwidth can quickly be determined.

Major Features:

1. Schematical capture:
   1. File merging
   2. Importing of (registered) Filter Wiz PRO files
   3. Rapid component (device) placement
   4. Fast editing of component values
   5. Op amp device database provides Gain BandWidth values for over 600 op amps
   6. Full circuit editing capabilities such as copy, cut and paste
   7. Annotation with text boxes and markers
2. Analog circuit simulation:
   • Both Filter Wiz PRO and Filter Wiz Lite can generate eSketch files
   • Automatic indication of when circuit is ready to simulate
   • View two graphs simultaneously
   • Two voltage probes - view both, either, or difference
   • Save previous traces to view up to 13 voltages or currents at once
   • Amplitude response (real, imaginary, dB, volts)
   • Phase and group delay responses
   • Input impedance
   • Component current, impedance and power dissipation
   • Sensitivity of output voltage to changes in component values
   • Transient response to impulse, step and "staircase" inputs
   • "Ideal" and "real" op amp models
   • Monte Carlo analysis
   • Parameter Sweep analysis
   • Pole-zero placement

Requirements: Windows 7, Vista, XP
