Abstract :
A Python computer program for calculation of distortion in the wide-band diode bridge track and hold amplifier (THA) is proposed. The computer program calculates the distortion of weekly nonlinear THA based on the KCL and the nonlinear-current method with an improved process. Simulations based on a commercially available 130 nm process technology are performed with the SpectreRF simulator. Comparative SpectreRF simulated results for the diode bridge THA have shown good agreement with those of computer program calculation, whereas the overall computational efficiency has been improved in a special evaluation.
