In this paper, a new voltage-mode (VM) first-order phase shifter (all-pass filter) employing only four NMOS transistors and
minimum number of passive elements (i.e. one resistor and one capacitor) is proposed. The proposed VM phase shifter has high
input impedance and does not require passive element matching constraints. Moreover, since only two NMOS transistors are stacked
between positive and negative supply voltages, the proposed circuit is suitable for low-voltage operation. Electronic tunability
can be provided easily by replacing the employed resistor with an NMOS transistor operating in triode region. Simulation results
based on 0.18 μm TSMC CMOS parameters with ±0.9 V supply voltages are given to demonstrate the performance of the proposed
phase shifter. |
