Paradice and Li LLP
CMOS analog circuits having a triode-based active load
An analog signal buffer is disclosed. The analog signal buffer may include a transconductance cell and an active load. The active load may load the current from the transconductance cell with a PMOS transistor and an NMOS transistor and provide a feedback resistance. A transimpedance amplifier is disclosed. The transimpedance amplifier may include a first cell configured to receive a first signal and output a second signal and a second cell coupled to the first cell. The second cell may include an active feedback structure configured to couple an output of the second cell to an input of the second cell.
