The energy gain of polarization-graded ferroelectric devices, configured as active transcapacitive elements, have been measured. Gain factors in excess of 1000 were obtained for small signal, static inputs; yielding charge gain amplifiers with gain factors of ∼150, remarkably similar to what is typically found for transistor current gain devices.
