Abstract

This paper presents two Cherry-Hooper amplifiers for bendable analog radio-frequency electronic systems fabricated in flexible self-aligned amorphous indium gallium zinc oxide (a-IGZO) thin-film-transistor (TFT) technology. The first circuit is a wideband single-stage Cherry-Hooper amplifier providing a voltage gain of 10.4 dB over a 3 dB bandwidth of 3.5 MHz and a gain-bandwidth product (GBP) of 11.6 MHz. For the second circuit, a two-stage Cherry-Hooper amplifier, a voltage gain of 33.3 dB with a 3 dB bandwidth of 400 kHz and a GBP of 18.5 MHz were measured. The simulations, which are based on a Rensselaer Polytechnic Institute-amorphous TFT (RPI-aTFT) model, are in good agreement with measurements.
