摘要：

A CMOS OTA for programmable HF filters is presented. When used in an OTA-C integrator, the unity-gain frequency phase error remains less than 0.3-degrees for frequencies up to more than one tenth of the OTA bandwidth. Since this phase error is preserved over the G(m) range of the OTA, the OTA is suitable for filters with a programmable transfer function.
